Minify JavaScript snippets and review compression ratio, comment removal, browser APIs, fetch calls, and console logs.
Input / Output
Input, output, and copy actions stay in this main surface. Examples and reference checks are separated below.
Local session
Input state is saved only in this browser so you can restore the last workspace without an account.
Open examples, checks, and related tools only after the primary input/output flow is done.
Review a JavaScript snippet
Format a snippet, copy the JavaScript review report, then minify or inspect API payloads before handoff.
Format the snippet and copy the review report with module, runtime, fetch, eval, and checklist signals.
Check compression, comment removal, and the minified review report if the compact version will be shared.
Inspect JSON or API payload examples referenced by fetch handlers before copying the snippet.

Review checklist
# JavaScript review report - Checked at: Browser copy time - Output mode: Minify - Characters: 37 - Output lines: 1 - Functions: 1 - Imports: 0 - Exports: 0 - Async/await: 0 - Browser APIs: No browser APIs detected. - Console calls: 1 - Fetch calls: No - Eval risk: No - TODO/FIXME/HACK notes: No - Compression ratio: 8% - Raw JavaScript is excluded from this report; attach a redacted snippet separately if needed. ## Review notes - Console calls are present. Remove debug logging before live use if needed. - The lightweight minifier removes comments and whitespace but does not perform AST-safe bundling. ## Review checklist - Run the snippet through project tests or a safe sandbox before shipping. - Confirm whether the snippet targets browser, Node.js, edge runtime, or a bundler. - Review fetch URLs, credentials, and error handling before copying network code. - Remove debug console output and TODO notes before production use. - Preserve license and handoff comments if minifying or pasting into docs.
