Technologies

The typical new JavaScript library shows high satisfaction but low usage, which can sometimes make selecting the right technology for your needs a bit tricky. This is where looking at the data can really help point you in the right direction.

Each line goes from 2016 to 2020. A higher point means a technology has been used by more people, and a point further to the right means more users want to learn it; or have used it and would use it again.

  • Some lines skip years.
  • Technologies with only one year of data are not shown.

This chart shows each technology’s satisfaction ratio over its total user count. It can be divided into four quadrants:

  • ASSESS: Low usage, high satisfaction. Technologies worth keeping an eye on.

  • ADOPT: High usage, high satisfaction. Safe technologies to adopt.

  • AVOID: Low usage, low satisfaction. Technologies probably best avoided currently.

  • ANALYZE: High usage, low satisfaction. Reassess these technologies if you're currently using them.

Note that TypeScript appears twice in the chart because it's included in both the JavaScript Flavors and Build Tools sections.

For each section, which percentage of respondents use (defined as having answered “would use again”) one, two, three, etc. technologies.
