What recruiters should know
JavaScript remains the most widely-deployed web language in 2026, appearing in the majority of frontend and full-stack job postings; 41.5% of recruiters actively seek JS developers (CoderPad 2025). TypeScript, its typed superset, has surpassed it as GitHub's #1 language by contributor count, but JS itself is non-negotiable for web development.
