What if my service works in FireFox and Chrome but doesn't work in Internet Explorer?

Question

JavaScript

What if my service works in FireFox and Chrome but doesn't work in Internet Explorer? Everything is ok in Chrome and Firefox, in IE you don’t understand what at all. Browser - IE10.

Answer 1

Well, here is one of two things - either forget about IE support, or adapt the entire service for it for a long and tedious time - look for polyfills for JS, take into account that half of the methods in IE have alternative names, or even work differently, sit around on CanIUse and more.
And here the important point is what kind of audience you are counting on. If these are grandparents who categorically refuse to switch to a new browser and sit with IE5, then of course, adaptation is needed. And if the service is related to web technologies or similar things, the probability that a freelancer who is friends with IE will visit it is equal to the chance of meeting a monkey in the desert.
Personally, I am in favor of adapting to the 10th and 11th , but not older, since there is generally an abyss ...
