Why TypeScript Is Now the Best Way to Write Front-End
97% of all websites now use JavaScript on the front end. Yet, as codebases scale, developers struggle to build, maintain, and extend sprawling front-end apps reliably.
Over half of JS developers have shipped bugs they attribute directly to lack of type safety. 62% say their projects have become harder to manage over time.
What if you could bring type checking and tooling from languages like C# and Java to front-end JavaScript?
Introducing TypeScript — a typed superset of JavaScript that compiles to JS. It brings the future of coding to front-end development today with bug prevention, editor tooling, and improved code intelligence.
Curious if using TypeScript for front-end is right for your JS application? Read on!
Importance of TypeScript in Modern Web Development
Have you ever worked on a complex JavaScript project that became tough to manage over time?
Is TypeScript primarily used for front-end or back-end development?
As web apps grow, keeping track of all the data types flowing through your code gets harder.
Well, that’s exactly why TypeScript for front-end has become so important!
TypeScript brings static typing to JavaScript, helping catch errors during development.
Here’s why you should be using it:
Catches More Errors Early On
Ever spent hours debugging, only to realize you passed a string instead of a number somewhere?
TypeScript catches those issues right away, making development faster.
Improves Collaboration
Making changes in big codebases can break things in confusing ways.
TypeScript catches unintended issues caused by other developers, reducing headaches.
Makes Code Easier to Understand
Adding types makes reading code much easier. Instead of deciphering types based on context, they’re explicitly labeled.
New developers ramp up faster, too.
Enables Powerful Tooling
Tools like auto-complete, refactoring, and intelligent code navigation rely on knowing data types.
TypeScript unlocks these helpful features for JavaScript projects.
Works Seamlessly with JavaScript
Already have a JavaScript codebase? No problem! TypeScript interoperates perfectly with existing JavaScript.
You can introduce a little or a lot over time.
For optimal results in leveraging TypeScript’s capabilities, hire front-end developers proficiently utilizing its features effectively.
Benefits of TypeScript for Front-end Development
As front-end applications scale in complexity, leveraging TypeScript can make development far easier.
How exactly, though?
Let’s unlock five stand-out superpowers it offers, revealing what TypeScript is used for:
Rapid Bug Identification
Tired of nasty bugs only emerging in production after days of testing? By checking types, TypeScript spots whole classes of errors early, like:
- Mistyped variable names
- Incorrect parameters passed
- Accessing wrong properties
Catching bugs before release allows more time to build features and less late-night debugging!
Easier Code Navigation
Ever gotten lost diving into a legacy codebase riddled with untyped JavaScript?
TypeScript’s explicit types help engineers and editors understand:
- Where interfaces are created
- What shapes data structures take
- How functions interact
This unlocks excellent code intelligence, refactoring, and organization abilities to tame disarray.
Lightning Fast Onboarding
Onboarding is quite challenging for front-end code.
TypeScript creates an automatic wiki/documentation by making the app structure explicit to new engineers.
With key interfaces, types, and architectural flows highlighted, quickly get new team members productive!

Writing Your First TypeScript File
With your project set up, it’s time to write some TypeScript code! Create a new file with a .ts extension in your project directory and start writing your TypeScript code. For example:
// hello.ts
function greet(name: string) {
return “Hello, “ + name + “!”;
}
let message = greet(“World”);
console.log(message);
Compiling TypeScript to JavaScript
Once you’ve written your TypeScript code, you must compile it to JavaScript before it can run in the browser. Open your terminal or command prompt, navigate to your project directory, and run the command below:
tsc hello.ts
This command will compile your hello.ts file to hello.js.
Running Your JavaScript Code
Finally, you can run your compiled JavaScript code in the browser or Node.js environment. Open your HTML file and include the compiled JavaScript file using a <script> tag:
<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset=”UTF-8">
<meta name=”viewport” content=”width=device-width, initial-scale=1.0">
<title>TypeScript Example</title>
</head>
<body>
<script src=”hello.js”></script>
