新推出的 JavaScript 套件獲得高滿意度與低使用率，顯示在選擇適合的工具時還是有些難度。這時候不妨看看調查資料吧，或許能為你指引正確的方向。
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.
滿意度 vs 使用程度
此圖表根據每項技術的全部使用人數顯示滿意比例，劃分成 4 個象限：
評估: 低使用度、高滿意度。是值得關注的技術。
採用: 高使用度、高滿意度。可以放心採用的技術。
迴避: 低使用度、低滿意度。近期最好避免的技術。
分析: 高使用度、低滿意度。如果正在使用這些技術，要進行重新評估。
Note that TypeScript appears twice in the chart because it's included in both the JavaScript Flavors and Build Tools sections.
Technology Usage Cardinality
For each section, which percentage of respondents use (defined as having answered “would use again”) one, two, three, etc. technologies.
