Age counts days since the employer published the posting. Around a third of sources publish only a coarse date such as “30+ days ago”, so the older end of this distribution is less precise than the recent end. It is the most-cited signal that a role may not be actively filled — a signal, not a verdict.

FAQ
Questions people ask
Is JavaScript in demand in London?
The openings count and the thirty-day change above answer that directly.
What does JavaScript pay in London?
See the percentile table — it uses local advertised salaries, not converted figures.
Figures cover 8,520 postings collected from public company career pages and applicant
tracking systems, last recomputed 2026-09-02.
“Posted N days ago” counts from the date the employer published the listing, not from when we
first saw it. A posting that has been up for months is a common sign it is not being actively
filled — though a long-lived listing is a signal, not a verdict.
