TypeScript is a superset of JavaScript that adds static typing to the language. It helps developers write more robust, scalable, and maintainable code by catching errors early during development. This guide introduces TypeScript in a simple, natural way.
TypeScript is a programming language developed by Microsoft. It builds on JavaScript by adding optional static typing and other useful features. TypeScript files have a .ts extension and are compiled into JavaScript to run in the browser or on a server.
Download and install Node.js to use the Node Package Manager (npm).
Run the following command to install TypeScript globally:
npm install -g typescript
Check the TypeScript version:
tsc --version
Create a file named hello.ts.
// hello.ts
function greet(name: string): string {
return `Hello, \${name}!`;
}
const message = greet("World");
console.log(message);
Compile the TypeScript file into JavaScript using the tsc command:
tsc hello.ts
This generates a hello.js file.
Run the generated JavaScript file:
node hello.js
name parameter in the greet function is explicitly defined as a string.The next article will cover:

Caching plays a pivotal role in web application performance, enabling faster responses and reducing server load. Both Next.js and React offer caching mechanisms, but they serve different purposes and are used in different contexts. This article delves into the details of Next.js unstable_cache and React Cache, highlighting their differences, use cases, and examples.
TypeScript is not just a theoretical tool; it shines in real-world applications, providing type safety, scalability, and enhanced developer experience. This article demonstrates practical TypeScript usage in real-world scenarios, helping to solidify the concepts learned earlier.
