suggestion: migrating to babel 8 in v3

[gameroman]

I think it would be a good idea to try migrating to babel 8 in v3(next) branch and I would like to help with that

I would prefer OXC over Babel.

OXC definitely would be much better, but for now upgrading the babel version would probably be easier

@ryansolid would you be interested in a PR for migrating to babel 8? (And for https://github.com/ryansolid/dom-expressions)
