Why Typescript Over Javascript

Typescript Programming

As a developer, I have always been intrigued by the endless possibilities that JavaScript provides. From building interactive websites to developing robust backend applications, JavaScript has been the go-to language for many years. However, in recent times, TypeScript has gained significant popularity and has become a preferred choice for many developers, including myself. In this article, I will delve into the reasons why TypeScript is worth considering over traditional JavaScript.

The Power of Static Typing

One of the primary reasons why I prefer TypeScript over JavaScript is its support for static typing. Unlike JavaScript, which is dynamically typed, TypeScript allows you to define the types of variables, function parameters, and return values. This brings great benefits in terms of code reliability and maintainability.

When using TypeScript, the compiler can catch type-related errors at compile-time rather than at runtime, which reduces the chances of encountering unexpected bugs in production. Furthermore, static typing enables better IntelliSense and code completion in editors, making development a breeze.

A Familiar and Easy Transition

If you are already familiar with JavaScript, transitioning to TypeScript is smooth and effortless. TypeScript is a superset of JavaScript, which means that any valid JavaScript code is also valid TypeScript code. This allows you to gradually introduce TypeScript into your existing JavaScript projects without having to rewrite everything from scratch.

Moreover, TypeScript offers a high level of compatibility with existing JavaScript frameworks and libraries. Whether you are working with React, Angular, or Node.js, there are excellent TypeScript typings available for popular libraries, ensuring a seamless integration of TypeScript into your workflow.

Enhanced Tooling and Developer Experience

When it comes to tooling and developer experience, TypeScript doesn’t disappoint. The TypeScript compiler, also known as tsc, provides robust error checking, code refactoring, and code navigation capabilities. It helps catch potential issues early on and enables better code organization and maintainability.

Additionally, TypeScript’s type system allows for better documentation and code understandability. By explicitly declaring types, developers can have a clear understanding of the expected behavior of various parts of the codebase. This can greatly improve collaboration among team members and make the codebase more readable and self-explanatory.

Long-Term Scalability and Maintainability

As projects grow in size and complexity, maintainability becomes a crucial factor. JavaScript, with its dynamic nature, can sometimes make it challenging to keep track of types and ensure code integrity over time. This is where TypeScript shines.

TypeScript’s static typing helps in catching potential issues early on and allows for easier refactoring. It enables developers to write code with confidence, knowing that the compiler will catch any type-related errors. This leads to more robust and maintainable codebases, making long-term scalability a breeze.


Choosing TypeScript over traditional JavaScript is a decision that can greatly benefit developers and their projects. The power of static typing, smooth transition from JavaScript, enhanced tooling and developer experience, and improved long-term scalability and maintainability make TypeScript a compelling choice.

While JavaScript will always remain an essential language in the world of web development, TypeScript offers a valuable alternative, bringing additional safety and reliability to our code. As someone who has made the switch and witnessed the benefits firsthand, I highly recommend giving TypeScript a try for your next project.
