JavaScript vs. TypeScript: Should You Switch?

JavaScript is a versatile language widely used for web development, offering ease of learning and flexibility. TypeScript, an extension of JavaScript, provides static typing and enhanced error-checking, making it a better choice for large, team-based projects. This article explores the key differences, advantages of each language, and guidance on when to use TypeScript, along with resources to start learning it.

🚀 JavaScript is everywhere! It is the most popular language for web development. But now, many developers are using TypeScript. Is it better? Should you switch? Let's find out!

1. What is JavaScript?

JavaScript (JS) is a programming language for the web. It helps create interactive websites. You can use JS to make buttons work, load content, and even build games!

Example

Here is a simple JavaScript code:

javascriptCopiarEditarfunction sayHello() {
  console.log("Hello, world!");
}

sayHello();

📌 This function prints "Hello, world!" in the console.

2. What is TypeScript?

TypeScript (TS) is JavaScript with extra features. It helps developers find errors before running the code. Big companies use TypeScript because it makes projects safer and easier to manage.

Example

Here is the same function, but in TypeScript:

typescriptCopiarEditarfunction sayHello(): void {
  console.log("Hello, world!");
}

sayHello();

📌 TypeScript adds : void to show that the function does not return a value.
