Yeah, of course performance gains can be had in JavaScript, and I will add to that fact with the experience that I've had when working with JavaScript developers: only one that I've ever known has ever considered performance and worked to produce performant JS before multiple users complained and an issue was raised. All others simply do not care about Javascript performance until there is an issue created to address it.
This single person is also the only JS developer I know who has any clue how to actually improve performance in existing code.
- littlestymaar 7y agoThis matches my experience as well (as a former full-time JavaScript dev), but in most cases, where JavaScript devs don't care about performance, you don't even need to understand how the machine works to speed things up. 90% of the time, the algorithmic complexity isn't thought at all and there are plenty of quadratic (or worse) behaviors everywhere.
