Support older browsers #28

Open marcioapm opened 2 years ago

marcioapm commented 2 years ago

Upgrading from 1.20 to 1.30 breaks on older browsers (IE10), because it doesn't support Map and Set, even though it's never used in the app.

I think the checks instanceof Set and instanceof Map should be preceded by a typeof Map !== "undefined" to ensure it is a platform that supports these.
