About the JavaScript ecosystem
JavaScript is the most-deployed language on the planet — npm ships 5M+ packages, Node.js powers half the cloud, and the browser is JavaScript-only. With that scale comes scale of abandonment: every measurement puts JavaScript's bus factor at the worst end of any language.
The npm deprecate command is the canonical signal that a package is no longer recommended. The GitHub adopt-me topic is the standard 'looking for a maintainer' signal. The looking-for-maintainer badge from shields.io is the README-level signal. All three are common in the JavaScript ecosystem.
The 2024 Harvard / Linux Foundation study found that the median bus factor for the top 100 npm packages is 1. The Bus Factor Explorer (2026) confirms this. For a single-maintainer npm package, the annual loss rate is 36% — meaning roughly 1 in 3 of those packages will be abandoned in the next year. The fix is a public handoff mechanism: adopt-me topic, the README badge, and a project page on BreakPoint.
The good news: the JavaScript community is large enough that most abandoned projects do get picked up. The median drop-to-first-PR on BreakPoint for JavaScript projects is 23 days. For a junior developer, this is the highest-leverage language to adopt in.
