A JavaScript Beautifier is a tool that takes messy, minified, or hard-to-read JavaScript code and formats it in a clear, readable, and consistent way. It adds proper indentation, spacing, and line breaks, making the code easier to understand and maintain.
Why use a JavaScript Beautifier?
Improved readability: Makes the code easier to understand, especially for teams or collaborators.
Easier debugging: Properly formatted code helps you spot errors and issues faster.
Consistent style: Enforces a uniform style across your codebase, reducing confusion.
Better maintainability: Clean, organized code is easier to update and expand.
Reverse minification: If you get a minified or compressed script, a beautifier makes it human-readable again.
For example, minified JavaScript like this:
javascript
function hello(){console.log("Hello, world!");}
After beautification, it becomes:
javascript
function hello() {
console.log("Hello, world!");
}
