Javascript runs in every browser differently. Some browsers support certain commands while others will not. I cannot find the exact website I'm looking for but you want some compatibility websites. The second and third links are likely better.

Do you need to use IE? Can you just change the default browser to be Chrome or anything else? Even Edge would do better than IE to be honest with you.
