Hello gang, What’s up? your friendly neighbourhood is here after long days. I was a bit busy with some Academic and cooperation stuff. So if you’re thinking “Why bother with TypeScript when JavaScript is doing just fine?” Well, buckle up because I’ve got some insights that might just change your mind. In this post, we’re talking about why we use should TypeScript for our MERN or MEAN Projects. So Let’s go

Why Developers love TypeScript

Type duh, type!

Imagine having a sidekick who tells you exactly what you’re dealing with at every step. TypeScript does just that with types. JavaScript is like the Wild West where anything goes. No sheriff to keep your variables in check. But TypeScript? It’s like hiring a sheriff. With types, you catch bugs before they even reach the saloon. You define what type your variables should be, and suddenly, your code is less error-prone. It’s like having a personal spell checker for your code.

IntelliSense

Imagine your code editor being your coding BFF. TypeScript makes this dream a reality. With strong type support, you get sweet IntelliSense that guides you through your code. It’s like having a co-pilot who knows your code better than you do. This not only speeds up your coding but also reduces those “wait, what was that variable name again?” moments.

Documentation Straight from the Code

TypeScript is like a neat freak’s dream. It forces you to document your code. Those types do you define? They’re like little love notes to your future self (and your team). Your code becomes self-documenting. It’s like writing a story where everyone knows the plot, the characters and the unexpected twists.

Embracing the Future of JavaScript

JavaScript is evolving, and so is TypeScript. TypeScript is like JavaScript 2.0 with extras. It supports the latest ECMAScript features and adds more tools to your belt. It’s like being the knight with a shiny, upgraded sword ready for whatever dragons JavaScript throws your way.

Easy to Team Collaboration

TypeScript is like a language interpreter for your team. It makes your code readable and understandable for everyone. When your teammate jumps into your code, they don’t need to decipher your chicken-scratch variable names, TypeScript is there to guide them. It’s like a universal translator for developers. Trust me I have experience with this kinda thing.

Finally what I want to say is “Why should you make the leap from JavaScript to TypeScript? It’s like upgrading from a bicycle to a hoverboard”.If you’re a MERN or MEAN developer itching for cleaner code, fewer bugs, and a smoother development ride, TypeScript is the next stop on your coding journey. just believe me now, your future self will thank you! Bye bye 🚀
