BigInt() incorrectly shown

The Glitch Editor is not showing the native function BigInt() which was added in Node 10 (Glitch using 12)
'BigInt' is not defined.
Please fix the editor to support the native function.

Hello, you might want to contact the folks at CodeMirror about this.

The current latest stable Code Mirror release already has BigInt() included.

In that case I’d recommend updating to the title to something like “update codemirror”.

It might be possible to replace the current codemirror glitch uses with a new one. Due to the bundling/webpack of javascript however, replacing is difficult since we have to figure out which part is part of the source code. Your best bet right now is to wait for glitch to update their version of codemirror
