技術

代表的なJavaScriptの新しいライブラリは高い満足度を得ていましたが、使用率は低いようなので、ニーズ合わせた正しい技術を選ぶのは一筋縄ではいかなさそうです。 このデータが、あなたを正しい方向へ導く手助けになるでしょう。

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.

このチャートは技術ごとにその満足度総利用数でプロットしたものです。4つの領域は、次のように読み取れます。

  • ASSESS: 利用率は低いが、満足度が高い。チェックしておくとよさそうな技術。

  • ADOPT: 利用率も満足度も高い。使っても大丈夫な技術。

  • AVOID: 利用率も満足度も低い。いまは避けておいた方がよさそうな技術。

  • ANALYZE: 利用率は高いが、満足度は低い。現在使っているなら、見直すとよさそうな技術。

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.
