TypeScript Vs JavaScript: Which One To Choose?

Let’s Understand JAVA

The most popular programming language in the world is JavaScript (JS). It is a high-level programming language that aids in the creation of interactive and dynamic websites. JavaScript is one of the essential technologies for web applications, alongside HTML and CSS, and is distinguished by its dynamic typing and just-in-time (JIT) compiler.

Because of the development and popularity of Node.js, JavaScript began to stand out as a server-side technology. Nonetheless, dealing with large and complicated applications with JavaScript is difficult since the code becomes more difficult to maintain and reuse as it expands. As a result, despite its advantages, JavaScript on the server (backend) made things messier and more difficult to manage. Microsoft released TypeScript to help with this problem.

Key takeaways from JavaScript

  • Most popular programming language;
  • Full-fledged, cross-platform, multi-paradigm, dynamic language;
  • Client-side and server-side implementation;
  • JIT compilation;
  • Compatible with all browsers;
  • Developed small scripts.

Let’s Understand TypeScript

Although JavaScript can handle hundreds of lines of code, it was not designed to handle large and complicated applications. As a result, TypeScript (TS) is a superset of JavaScript and serves the same goal. However, because it is tightly typed and includes compile-time error controls, it was designed to handle and develop larger programs.

Key takeaways from TypeScript

  • A superset of JavaScript, thus compatible with JS libraries
  • Strongly typed, compiled language can follow OOP principles
  • Easier to debug
  • Provides static typing
  • Offers full-fledged IDE support
  • Can convert its code to JavaScript code

Difference between TypeScript and JavaScript

The first distinction to note is that, whereas JavaScript is a scripting language that aids in the creation of interactive and dynamic web pages, TypeScript is a tightly typed superset of JavaScript.

To summarise, TypeScript is JavaScript enhanced with features designed to overcome JavaScript limitations, particularly regarding static type and code complexity.


On the one hand, there is no need to compile when utilizing JavaScript. Because it is an interpreted language, faults can only be discovered when the program is running. To put it another way, it must first be run in order to be tested and determined whether it is genuine or not. As a result, finding problems and errors in the code may take a long time.

TypeScript, on the other hand, offers a compile-time error mechanism that compiles the code and checks for compilation faults in the syntax, as the name implies. Before running the script, this functionality can save developers a lot of time. It also helps the business, not just the engineers, by preventing some errors from reaching production.

Is JavaScript an object-oriented programming (OOP) language?

ECMAScript is a scripting language standard that includes rules, standards, and other information about what a scripting language should include. JavaScript is a scripting language that adheres to the ECMAScript standards. Because such requirements might change and new ones can be added, multiple ECMAScript versions exist. This version introduced modules, classes, arrow functions, enhanced object properties, and other exciting features.

Is TypeScript an object-oriented programming (OOP) language?

The solution to this question is a little more complicated. On the one hand, TypeScript includes classes and other capabilities that enable developers to adhere to OOP ideas and approaches.

How to Start Learning?

Developers must first master JavaScript before they can learn TypeScript. Because both languages share the same syntax and run-time behavior, the more a developer understands JavaScript, the easier it will be to learn TypeScript (except the fact that TS has a compile-time checker).

JavaScript has a large community and a lot of resources because it is the most popular language. Because the way tasks are executed is similar in most circumstances, TypeScript developers can profit from those resources as well.
