QUESTION
I want to understand why these two equal benchmarks have different results on these two different platforms.
In the first one arr.filter(Boolean).join(" ")
is the fastest, in the second one is the slowest!
Why?
The code I'm using is this:
...ANSWER
Answered 2021-Mar-26 at 21:15This is a prime sample why you can't trust js benchmarks. The way the tests are run, the boilerplate code to do it, everything has an impact. The engine optimizes to each situation and the results, well, are garbage in the end.
Read this: https://medium.com/cacher-app/how-js-benchmarks-lie-fa35fa989ee0
Or the discussion on: Which JS benchmark site is correct?
When I come into an issue with my code, I test it in that exact context as this is where it will actually need to go fast. This means that 1 solution does not fit all, many, but not all.

I have a selection box that makes use of jquery $.post()
on the change to parse the data in php and returns the results through postit.done()
and renders it in a specified div. This works fine.
The problem is in the returned parsed results there is a class for a tool tip that is suppose to respond on the hover but does not.
This is the code for the selection box:
...ANSWER
Answered 2017-Mar-26 at 01:33This would generally be considered as code-injection, and would not be executed by any modern browser.
Bring the rendering/event logic back into JQuery and use the PHP to provide the data upon request instead. As long as you use the browser's Javascript engine for your rendering and event handling, then all will be well.
