Issue originally made by @nunocastromartins

Bug information

  • Babel version: 6.9.1
  • Node version: Website's "Try it out"
  • npm version: Website's "Try it out"

Input code

a[`${b++}`] **= 1

Description

Input:

a[`${b++}`] **= 1;

produces:

var _a = a;
_a["" + b++] = Math.pow(_a["" + b++], 1);

instead of:

var _a = a;
var _ref = "" + b++;
_a[_ref] = Math.pow(_a[_ref], 1);

Also, is there any reason behind the var _a = a;?
