IE 11 bug - SCRIPT1053: Const must be initialized

[mbkupfer]

On IE 11, I'm getting an error that that says Const must be initialized

when I open up the dev console debugger, it takes me to the following block:

 scale.domain = function(_) {
    if (!arguments.length) return domain.slice();
    domain = [], index = new Map();
    for (const value of _) {
      const key = value + "";
      if (index.has(key)) continue;
      index.set(key, domain.push(value));
    }
    return scale;
  };

I've seen similar issues brought up for other projects in github, the most promising being vercel/next.js#4334. I tried to use babel/polyfill as one of the comments mentioned, but that did not fix the problem.

Please disregard. I just read the release notes for v3.0.0.

Installing the latest 2.x fixed this issue.

For future reference, that command I used:

npm i d3-scale@2.2.2
