Thank you. I see, one way around this is to use a transpiler such as Babel or Rollup. These converts your ES6++ code into ES5 so that other browsers like IE can read the code. Think of this like one person speaks Italian, the other one French and you have middleman (transpiler) that translates the language. Transpilers are mainly made to solve the issues between “My browser does not support this etc”.
Check out this article I made on how to setup a transpiler and run ES6 code, click here.
