Momentum
Each signal is ranked as a percentile among the technologies that have it. A signal without enough history is not counted, and never shown as zero. How momentum works
Momentum
Collecting1 of 5 signalsNo score yet. Momentum is published only when at least 2 of the 5 signals have history. Jest has 1, so there is no single number: each signal is shown on its own below. It is not a zero, and nothing is estimated in its place.

Adoption by registry
The growth of Jest’s own packages, one row per registry in that registry’s own unit. Registries count different things over different windows, so they are never added together.

|---|---|---|---|---|
| npm | Downloads (30 days) | 12.4B → 12.3Bdownloads / 30 days | −0.6% · 30d | 54 |
