Over twenty years have passed since JavaScript first appeared on the computer scene. In that time, it has grown to have a sizable following of devoted supporters who utilise it for a variety of endeavours, including gaming, interactive UIs, server apps, online and mobile development, and artificial intelligence projects. Nevertheless, it had a number of problems, and in order to address them, its rival TypeScript appeared. Are they interchangeable, and what distinguishes them from one another? Let’s together research this.


JavaScript is a scripting language for creating interactive web pages. It followed client-side programming standards, meaning it operates in the user’s web browser without requiring any resources from the web server. Javascript can also be used in conjunction with other technologies such as REST APIs, XML, and others. The goal of creating this script is to make it a supplementary scripting language in the same way that Visual Basic was to C++ in Microsoft’s language families. JavaScript, on the other hand, is not intended for huge, complex applications. It was designed for apps with little than a few hundred lines of code!


TypeScript is a JavaScript programming language from the current era. It is a statically built language for writing concise JavaScript code. It may be run on Node js or any browser that supports ECMAScript 3 or later. TypeScript has static typing, classes, and an interface. Adopting Typescript for a large JavaScript project can result in more robust software that is easily deployable alongside a standard JavaScript application.


JavaScript is a programming language that aids in the creation of interactive web pages, whereas TypeScript is a modern JavaScript development language. In contrast to JavaScript, which lacks such a concept, TypeScript employs ideas like types and interfaces to describe the data being used. Many npm packages for Typescript either include static type definitions or offer an easy-to-install external one. Without requiring a build phase, JavaScript allows for code exploration and creation. Prototyping is a function of Typescript. JavaScript is devoid of this capability.

Since TypeScript is a superset of Javascript, it contains all the functionality that Javascript does, along with a few extras. It is advantageous to use TypeScript because it only compiles to Javascript. Currently, JavaScript is widely used and extremely popular, yet due to its advantages over JavaScript. The use of TypeScript is also rapidly growing. Although TypeScript is fundamentally JavaScript, there is no way that it can replace JavaScript; yet, it is feasible that it will alter how programmers create code for websites. Typescript supports module vs javascript won’t support module.


The notion that one language can outperform another or that one is superior to the other is entirely your choice. JavaScript is a foundational programming language that remains many developers’ first choice due to its versatility, extended functions, and vast community. It is appropriate for small projects requiring dynamic web applications, as well as mobile and desktop apps. TypeScript, on the other hand, is an excellent solution for developers working with a huge codebase. It is a new language, but it is ideal for complex projects due to its OOP concepts and generic features, as well as its rich IDE support. If you want to get more knowledge about JS and TS then you must do consultant with the Fullstack web developer from the custom web development company. It can provide developers with what JavaScript lacked. As a result, selecting one over another is entirely up to you and should be based on the project.
