Question

I have a reactjs app written using ES6 standards, and I use webpack to build it. The webpack loads the js modules using <

OK, I had the same issue, but in my case that was quite different, so basically you need to include script in the index file as below:

But in my case, I already included that, after some investigations I found out that my proxy blocked the script...

So make sure you include it in index.html and also make sure that you have access to the script from where you need it to avoid the error happening...best way just copy and paste the url in the browser...

But now which we get to this point, it's not talking about Symbol itself, what's Symbol which can not be recognised in IE?

The Symbol() function returns a value of type symbol, has static properties that expose several members of built-in objects, has static methods that expose the global symbol registry, and resembles a built-in object class but is incomplete as a constructor because it does not support the syntax "new Symbol()".

Every symbol value returned from Symbol() is unique. A symbol value may be used as an identifier for object properties; this is the data type's only purpose. Some further explanation about purpose and usage can be found in the glossary entry for Symbol.

The data type symbol is a primitive data type.
