Java Script Vs. TypeScript

JavaScript is a programming language that lets you create dynamically updated content, control multimedia, animate images, and much more. While TypeScript is a strict syntactical superset of JS that compiles to plain JavaScript. So, the question is, which one is perfect for your next web application?

That depends on a few factors. JavaScript may be the better choice if you're just starting with programming. It's easier to learn than TypeScript, and more information and resources are available for JavaScript than for TypeScript.

In contrast, if you're looking for better performance and scalability, TypeScript may be the way to go. It can assist you in catching errors early on and writing cleaner code. And since TypeScript is becoming more popular, there's likely to be more information and resources available for it in the future.

Let's go through the basic insights of JavaScript and TypeScript to comprehend which one to choose - TS vs JS.

What is TypeScript?

TypeScript is an open-source programming language introduced by Microsoft back in 2012. From 2012 to 2022, it has become the first choice for almost 34.83% of web developers globally.

It is a typed superset of JS that compiles to plain JavaScript. It adds syntax on top of the JS to let developers add the data types within the code to improve its ability to catch errors.

TS is designed for large and complicated application development and transcompiles to JavaScript. One can use the TS to develop JavaScript applications for client-side or server-side execution.

Difference between TypeScript and JavaScript

After thoroughly discussing JavaScript, TypeScript and its pros and cons, it's time to put light on TypeScript vs JS comparison. We have enlisted the key differences between TS and JS to assist you in picking the best-suited language for web development.

  • TS is a typed superset of JS that compiles to plain JS. In Contrast, JavaScript is a dynamic language that doesn't support types. This difference allows TypeScript to offer features such as static type-checking, while JavaScript cannot.
  • TS code must be compiled, while JS code is interpreted at runtime. Finally, because TypeScript is a superset of JavaScript, all the JavaScript code is also valid TypeScript code.
  • TypeScript supports classes, interfaces, and modules, while JavaScript does not. It enables coders to organize and reuse the code in TS easily.
  • TypeScript has an optional type system, while JavaScript does not. It enables TypeScript to offer static type-checking, which can help find bugs early in the development process.
  • TypeScript code must be compiled, while JavaScript code is interpreted at runtime. This difference can impact performance and debug.

TypeScript – the future of web application development 2023

Why, in our opinion, it's better to choose TypeScript for web applications? When picking a programming language for web development, there are many factors to consider. One of the crucial ones is whether the language is easy to learn and use. Another critical factor is how well the language works with existing code and libraries.

JavaScript has been the standard for web development for many years. However, TypeScript is a newer language that has recently gained popularity. So, TypeScript or JavaScript, which one should you pick for your next web project?

There are several reasons why Typescript may be a better choice than JavaScript for web development, such as:

  • TypeScript is a superset of JavaScript, which includes all of the features of JavaScript and more. That makes it easier to learn for those who are already familiar with JavaScript syntax.
  • TypeScript provides stronger type-checking than JavaScript. It can prevent errors in your code and make it easier to catch bugs before they cause problems in your application.
