Beautify JavaScript and JSX code with consistent spacing, semicolons, and indentation using Prettier
Ctrl+Enter to format
JavaScript code accumulates inconsistencies quickly across a team: some engineers prefer single quotes, others double; some include semicolons, others omit them; callback-heavy legacy code and modern arrow functions live side by side in the same file. QuickKit's JavaScript formatter runs Prettier under the hood — the industry standard for JS formatting — so your output is the same as what your CI pipeline enforces. Paste minified JavaScript from a bundle, unformatted AI-generated code, or a colleague's inconsistently styled file and get back clean, readable, consistently formatted JS that any modern linter will approve. Works with ES6+, CommonJS, AMD, async/await, optional chaining, nullish coalescing, and JSX.
