Results of MDN APIs & JavaScript survey

[foolip]

These are the results of one of the surveys designed in #196. 5% of visitors to the APIs and JavaScript sections of MDN were shown this survey between Oct 31 and Nov 7, and there were 772 responses. It was possible to select up to 5 options. The question was:

For your needs as a developer, which features should be improved across browsers in the coming year? This means enabling support or fixing bugs. Please select up to 5. (This is not a complete list, other features may also be planned.)

Also sharing a figure from the PDF for this. It's hard to read, but makes it visually obvious that some options are very close, and the relative order of them isn't very meaningful:

Getting a rough idea of confidence intervals similar to #245 (comment), the widest confidence interval is for the option closest to 50%, which is Web Components at 38.7±3.44%.

While that option stands out quite a lot, the order of many of the others is uncertain, and I'll be talking about top/middle/bottom thirds in comments. (Split as top 6, middle 7, bottom 6.)
