What is TypeScript, really?
TypeScript is JavaScript with type checking added. Think of it as the difference between sending a SMS and sending a courier with tracking — same content, but you know exactly where it is and what is in it. Microsoft built it, and now most serious frontend codebases (VS Code, Slack, Asana, Notion) run on it.
Why learn it in 2026?
If you are doing JavaScript for a living, your next salary jump is TypeScript. Most senior frontend roles in Bangalore now require it. It catches bugs before users see them, which managers care about.
Slight learning curve if you have never used a typed language before. Stick with it for a week — once it clicks, you will not want to go back. Generic types still confuse everyone, including me sometimes.
What it looks like
// Catch bugs at compile time
interface User {
id: number;
name: string;
email: string;
}
function greet(user: User): string {
return `Hello, ${user.name}!`;
}
What you can build with it
