Foreach loop

[ArunPatal]

Describe the bug

Hello, i am using ace editor in Firefox 34 (win xp).

In recent changes browser throw an error in line 17339.
TypeError: activeIndentGuides.forEach is not a function

---

Changing

 activeIndentGuides.forEach(function (el) {
            el.classList.remove("ace_indent-guide-active");
        });

To

for(var i = 0; i < activeIndentGuides.length; i++){
        	activeIndentGuides[i].classList.remove("ace_indent-guide-active");
        };

will fix this.

Please make this change to original source.

Thanks

Expected Behavior

avoid foreach loop to make it work in old browser as well.

Current Behavior

foreach throws an error

Reproduction Steps

 activeIndentGuides.forEach(function (el) {
            el.classList.remove("ace_indent-guide-active");
        });

Possible Solution

change line 17339

for(var i = 0; i < activeIndentGuides.length; i++){
        	activeIndentGuides[i].classList.remove("ace_indent-guide-active");
        };
