[Solved] Is the JavaScript Set data structure supported by all the browser?

by


MDN has the following about basic support:

  • Chrome 38 and up
  • Firefox (Gecko) 13 and up,
  • Internet Explorer 11 and up,
  • Opera 25 and up,
  • Safari 7.1 and up

Other features may or may not be available, see the linked page for reference.

It is part of the ECMAScript 6 specification, so you it will be well-supported in the future, but right now, I would not depend on it. But you might use a tool to convert your ECMA 6-complaint code to ECMAScript 5, as it is backwards compatible.
