Do I need to remove event listeners in 2016?

Question

This question was asked and answered in 2011. However, the web scene has taken a considerable change and now IE6 and IE7 are out, IE8-10 are barely out (under 1% each) and only IE11 is still there.

So, in 2016, do you need to manually remove event listeners to avoid memory leaks? Consider only IE11 for the answer please. I am asking because I created a small library as an alternative to jQuery and would love to know if I have to remove them manually first. Of course the question is when using vanilla javascript, not jQuery.

Answer 1

No

See these answers:

• If a DOM Element is removed, are its listeners also removed from memory?

Also:

• This article claims the DOM + JS reference cycle memory leak was fixed in IE8.
