JavaScript's "for of" loop is not supported in IE 11, causing it to fail

Here is a piece of code I'm using to select and remove a d3.js node:

 if (d.children) {
        for (var child of d.children) {
            if (child == node) {
                d.children = _.without(d.children, child);
                update(root);
                break;
            }
        }
    }

While this code functions correctly in Chrome and Edge, it encounters an issue in IE-11 with a missing semicolon. It seems to be related to the use of 'of' for looping. Has anybody else faced this problem in IE before? If so, how did you resolve it?

Answer №1

This particular feature is part of ES2015 (also referred to as ES6) and is only compatible with modern browsers. Typically, this concept would be used in conjunction with a transpiler like babel to cater to older browser versions.

If you're curious about the compatibility of the for...of statement, you can refer to the comparison table here: https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Statements/for...of
