JavaScript evaluation spans a wide surface area: DOM manipulation, event delegation, Promise chains, async/await patterns, module bundlers, and modern ES2022+ features. A single session might have you reviewing a React hook for stale closure bugs, then evaluating a vanilla JS event listener for memory leak potential, then assessing whether a module uses ESM or CommonJS appropriately. Tasks emphasize clarity, modern best practices, and browser compatibility—AI often writes technically working code that fails in edge cases or older environments. Framework knowledge (React, Vue, Svelte, Node.js) expands the task types available to you and increases your earning potential.
You will review AI-generated code snippets for syntax errors, logic bugs, and efficiency. Platforms like Mercor, Micro1, and SME Careers regularly post JavaScript code evaluation roles.
You can expect to earn up to $35-$80/hr depending on task complexity and your proficiency level. Note that platforms like Mercor scale pay based on location—US-based workers typically earn more than those in other countries. These are estimates based on aggregated job listings.
