This package claims to support IE 11 on the readme. But that stopped working on a minor release.
From what I can gather, v8.3.0 introduced stringify.js which utilises default parameters. IE 11 does not support default parameters and thus fails.

I've managed to fix this issue by using babel, but its worth:

• Not using modern syntax in minor releases until checking they work in all browsers you're supporting
• Either remove IE 11 support or remove usage of default params
• Using some rollup plugin to compile down to a compatible version
