Free JavaScript and TypeScript code formatter. Beautify and clean up messy JS/TS syntax with configurable indentation and zero server uploads.
Loading tool...
The JS/TS Formatter beautifies and minifies JavaScript and TypeScript source code, formatting indentation, bracket spacing, semicolons, and quotes according to clean code standards.
Parses JavaScript (ES6+ / ES2024) and TypeScript syntax trees, enforcing consistent 2-space or 4-space indentation, line wrapping, comma placement, and bracket alignment without altering runtime code execution logic.
function calculateTotal(items){let total=0;items.forEach(item=>{total+=item.price*item.qty});return total;}function calculateTotal(items) {
let total = 0;
items.forEach((item) => {
total += item.price * item.qty;
});
return total;
}Adds consistent line breaks, 2-space indentation, and readable bracket padding.
The formatter uses a client-side lexical tokenizer that applies standard 2-space indentation, consistent line breaks after semicolons and braces, and uniform statement spacing without sending code to an external server.
No. A code formatter only alters whitespace, indentation, and stylistic syntax (like quotes). It mathematically guarantees that the execution logic of your code remains identical.
It formats standard JavaScript, TypeScript statements, object literals, and functions. For deeply nested JSX or specialized DSLs, dedicated AST compilers like Babel or Prettier are recommended for complete syntactic tree formatting.
