For the second time the report benefits from the contribution of "dataviz expert", Amelia Wattenberger in updating a chart summarizing the changes over time in respondents' opinions of the technologies included in the survey.
The lines now go from 2016 to 2020 (the brighter end where the label is shown). A higher point means that a technology has been used by more people and a point further to the right reflects popularity - more users who have used it would use it again or more people want to learn it.
TypeScript was the technology with the greatest growth in usage year on year and Graph QL the technology with the highest interest - the one developers are most interested in learning once they are aware of it.
Testing Library, which isn't included in the chart as it was only introduced in 2020 takes the award for highest satisfaction. With a rating of 97% it narrowly beat Jest (96%), another testing framework.
In this graphic the bigger the circle the more respondents are aware of it and the bigger the proportion that is bright the greater the usage. In the report it interactive so that you can see how many respondents are are aware of a feature (the outer circle) and how many have used it (the inner circle) and the ration between the two. Compared to last year, more features are included and on the whole it is the new features that are least used. For example, Big Int is hardly used - but then having an integer with as many integers as you like isn't something everybody would want. Private Fields however is more mainstream and I can't explain why its adoption is lagging behind that of Optional Chaining and Nullish Coalescing. While WebAssembly isn't new, it is still used by only a tiny proportion of respondents and again WebGL stands out as under-appreciated. Its usage ratio has hardly improved from last year, when I commented:
WebGL graphics isn't for everyone but surely more than just 20% could benefit from using it?
The survey also continues to gauge overall opinions:
