@stevenrays p5.js should still be working on IE 11. Is there something specific that is not working on IE 11 that you found?

Hi, so while I was just checking the cross browser compatibility of things while working on the FES, I did come to know that p5.js 1.0.0 indeed does not work on IE 11. Version 0.9.0 seems to be the last version to work on IE 11. For all p5 versions after it, the initialization itself crashes.

The stacktrace of the error is

ReferenceError: 'Symbol' is undefined
at p5 (https://cdn.jsdelivr.net/npm/[email protected]/lib/p5.js:62900:19)
at _globalInit (https://cdn.jsdelivr.net/npm/[email protected]/lib/p5.js:62466:17)
at invokeCallback (https://cdn.jsdelivr.net/npm/[email protected]/lib/p5.js:33807:21)
at publish (https://cdn.jsdelivr.net/npm/[email protected]/lib/p5.js:33790:21)
at flush (https://cdn.jsdelivr.net/npm/[email protected]/lib/p5.js:33506:19)

Symbol is not supported by Internet Explorer.
It happens inside the p5() constructor. The error is caught in a try-catch block so it can't be seen on the console but can be seen using a debugger, but it prevents the constructor from calling setup().
The error happens on a line that that is not present in the source but in the final built version, probably added by Babel.

I don't know enough about babel to know why this is happening. @outofambit Can you have a look at this?

[outofambit]

@limzykenneth yes, i can take a look at this! there's probably a small config tweak i need to make to babel. thanks for investigating this @akshay-99!

Yes, so here are some screenshots of what is happening for me in IE 11. I first received an error with p5.sound.js and then removed it, and got an unspecified error.
