How can you choose between JavaScript and TypeScript?

JavaScript is a scripting or programming language that allows you to implement complex features on web pages. According to the official 2023 Stack Overflow survey of more than 90,000 developers, they ranked JavaScript as the most popular technology. 2023 is its eleventh year as the most commonly-used programming language. Here are 3 advantages of JavaScript over other programming languages: - Ease of learning - Large community - For both front-end and back-end JavaScript is the king in the software development realm. It's everywhere on websites & apps. It's a must to master JavaScript as a front-end developer.

This is indeed true, and it continues to change the lives of Front-end developers. The one thing this article can add to give more clear picture before someone jumps to learn this language, and make it a choice is the challenges we might face while learning this language. Like loosely coupled in respect of types. Error handling is good, but need proper understanding, else, JS can become challenging in this sector as well, and a lot of developers still complaints about JS due to the same reasons.

Choosing between JavaScript and TypeScript depends on several factors, including the project requirements, team expertise, and personal preferences. Here are some considerations to help you make a decision: 1. Project Requirements: Consider the complexity and scale of your project. TypeScript is a statically typed superset of JavaScript, which means it offers additional features like static typing, interfaces, and classes. If your project is large, requires complex data structures, or demands strict type checking, TypeScript may be a better choice. On the other hand, if your project is small, simple, or requires quick prototyping, JavaScript might suffice. 2. Team Expertise: Evaluate the skills and experience of your development team.

JavaScript works well as independent, but when considering a substantial and critical project, TypeScript becomes indispensable from this point forward. Typescript can be used with api mapping with checking strict type of data.

JavaScript was born in the '90s and is the backbone of all modern frameworks, is dynamically typed, allowing quick dev but risking runtime errors. It's one of the best languages for beginner programmers to learn and will not disappear.

TypeScript basically extends the ability to typecast variables and return types. Those working with strictly typed languages might find it very intuitive. But no browser can run typescript out of the box. It needs to be compiled to JS which is the task for TypeScriptCompiler(tsc). It may be outlined that for very small tasks, TS may not be a very good option. But for a larger code base, definitely. TS can save a lot of development time when it comes to debugging errors for interfaces and for code bases where data is particularly layered. It will definitely help ensure that the DTOs are intact even for the front end development.

I think your post is well-written and informative. You’ve covered all the important points and presented them in a clear and concise manner. To make it more powerful, you could consider adding some examples or case studies to illustrate your points. This would help readers better understand how to apply your advice in real-world situations.

A valuable discovery I made while working with TypeScript is that runtime issues due to data types are largely avoided, as type-related problems are typically identified during the compilation phase. However, a recurring challenge I've encountered is the absence of TypeScript support in certain packages. In such cases, I've had to manually construct interfaces when utilizing less common yet beneficial packages.

TypeScript is a programming language that's built on top of JavaScript. It adds a cool feature called "static typing," which means you can say what type of data a variable should hold. This helps catch mistakes before you even run your code, which is super handy. TypeScript works with all the latest JavaScript stuff and brings some extra tricks like union types and generics. The best part? When you're done writing TypeScript, it turns into regular JavaScript, so it can run in any browser or system. It's like getting the best of both worlds – strong error-checking during development and compatibility when it's time to share your work.

One of the best places where TypeScript shines the brightest is in larger projects with complex business and `more bots on the ground`. You can always say that you better go with TypeScript on all projects, but in real life, there are definitely use cases where pure JavaScript is the way to go.

One things I have found insightful about this pointer is the reference given to the developers who are trying to start their learning journey of this beautiful language JavaScript. "JavaScript is an advantageous language for front-end development, as it is easy to learn and use, especially if you are already familiar with other languages like Java, C#, or Python." You can also mention about how not only web, but JavaScript can be widely used for developing backend APIs as well, which makes it a complete package altogether for development, and not look anywhere.

JS it's best suited for smaller projects, with simpler business logic where the budget, experience, and timeline don't let you go with TypeScript.

Using JS is usually a good option for most small and inexperienced team, especially creating a mvp because its faster, cheaper and your team knows it in an out, even an intern in your team would be knowing it. It also saves so much efforts, and cost for a smaller team to train people in ts, and frankly my strongest opinion is doing js with best practices is mostly sufficient for a lot of smaller use cases

Javascript has many reasons to get started in software development. First & foremost point is that it is easier to learn. And one person with lesser experience in JS can also start contributing immediately. It also has a lot of community support so there is always someone to help you out with issues.

Versatility: JavaScript is a very versatile language. It can be used to develop a wide variety of applications, including web pages, web applications, mobile apps, games, and desktop applications. Popularity: JavaScript is one of the most popular programming languages in the world. This means that there is a large community of JavaScript developers and a wide range of resources available to help you learn and use the language. Ease of use: JavaScript is a relatively easy language to learn and use. Performance: JavaScript is a very fast language. This is because it is interpreted directly in the browser, without the need for compilation. Community support: JavaScript has a large and active community of developers.

Even if it is not entirely false, I disagree with "enforce consistent and clear coding standards and conventions", Typescript by itself if it's not properly use can obfuscate the code a lot, the code conventions and good practices are what really enforce the consistent and clear code. As it is mentioned in this article, typescript is a superset of JS so basically by changing the extension of a file from js to ts we can say that the code is "typescript" even if not all ts features are used

TypeScript offers advantages over JavaScript, such as reliability, maintainability, and scalability. It detects errors at compile time and enforces clear coding standards. Its features support large projects, providing future-proofing by transpiling to any JavaScript version. It's ideal for projects requiring strong structure.

Typescript offers you more readable & understandable code. It creates the typed variables which will not change their type. It also integrates object oriented concepts which makes it easier for backend developers to pick it up easily.

Type safety: TypeScript's type system can help to prevent errors and make your code more reliable. For example, TypeScript will warn you if you try to assign a string to a variable that is typed as a number. Readability: TypeScript's type annotations can make your code more readable and easier to understand. For example, if a function takes a parameter that is typed as an object, you can clearly see what kind of object the function expects. Maintainability: TypeScript can make your code more maintainable by helping you to prevent errors and by making your code more readable. Tooling support: TypeScript has excellent tooling support, including IDE integration, code completion, and type checking.

I would mention that the size of the project should be considered. Larger projects might be better maintained if they are in typescript

This whole article is not posing the question correctly. TypeScript is a superset of JavaScript. In other words, it's still JavaScript. TypeScript provides you with much more maintainable, understandable code, and helps you reduce potential developer errors. For me it's a no brainer, if you don't use TypeScript, it's due to laziness, because there is literally 0 benefit to vanilla JS compared to TS.

TypeScript will be indeed a better choice in smaller or bigger projects, but for a project where a lot of team members are working, I think it should be a "must" choice for the organisation making decision on choosing the language for the project.

I would definitely leverage Typescript for all new Javascript based project you are starting. It makes your code more predictable and catches bugs early on. I don't really think there are any disadvantages, besides perhaps having to learn how to utilize Typescript most effectively. But it's 2023, as a Javascript developer, you're bound to come across Typescript anyway so better get into it sooner than later.

In today's technological landscape, incorporating strict typing into your project can significantly expedite debugging and development. While it might require more time initially, the investment is undoubtedly worthwhile. However, if you're working on a proof of concept, using Typescript might not be as pertinent unless you're proficient with it. Additionally, I've observed some individuals excessively using Typescript, complicating the process. It's vital to recognize that languages and frameworks are merely tools to aid our tasks. Employ them only when they enhance the value of your project.

Just to add, bluntly I think that TS overall is a net win in productivity and safety. Alongside eslint, it’s an automated way to increase code quality, and these days I’m not sure why you would use just JavaScript, besides as you say the case where an app is migrating over.

I don’t really agree with using typescript for logic and components and javascript for the UI. The only reason to use javascript in a project that uses typescript is because we are re-using and existing library or legacy code. This might be a UI component of course, but proving such example in this kind of article might leed people to believe that typescript is for “backend” and javascript is for “frontend”. Another thing is that while you can always use a javascript syntax in typescript, the viceversa is not valid.

JavaScript and TypeScript can be used simultaneously in a project, catering to different needs. TypeScript might handle core logic requiring type safety, while JavaScript could manage the UI layer. This combination allows leveraging both languages' strengths, ensuring an effective, flexible development process

In my experience, if you already have a project that is completely JS, you can slowly migrate to TS. When you add new modules or files make sure it's typescript. Typescript provides additional layer of security and can help in catching potential bugs before hand.

The decision between JavaScript and TypeScript depends on the project’s size, complexity, team's background, and tools used. TypeScript might suit larger, structured projects, especially with developers familiar with typed languages, while JavaScript may be more appealing for simpler, flexible applications.

As you begin your journey to become a programmer, the need to tackle more complex topics will appear and a small project that started as a simple HTML will get a form, maybe some styling, some animations, maybe a backend with a database, a cool feature and as a novice programmer, reading on the internet, you will come across JavaScript and will be one piece of that puzzle that started your programming career.

JavaScript its fine for an MVP, but if we are talking about a large and serious project, TS is essential after this part. There's so many things that can go wrong using vanilla JavaScript and no advantages, except for laziness and hiring trainee developers who doesn't now typescript.

Leaving aside the technical factors between the two, always consider the skills your team share, your timeline for the project, and how easy it is to find new people with said skills. It's often hard to measure how much time a company wastes dealing with small problems that come with lack of knowledge, training, and hiring processes. Keep it simple.

The development team skills and experience are the most important part of the language choice. Highly experienced software engineers (especially full stack developers) with experience in C# will find it easy to understand Typescript and adapt to its concepts. If the team consists of junior developers who are not familiar with strongly typed languages and the need is to just create a simple prototype using dynamic programming, JavaScript will probably be the easiest way to go. JS has definitely a faster learning curve and also all modern browsers support the language natively. However, bear in mind that by using TS you will encounter the errors at the compilation stage, whereas with JS you will go the hard way and discover errors at runtime.
