Description
Requested Update
es-check can have a function to tell us the minimum version of all ES versions that allows a file to parse normally.
This can be done by simply testing against all parsers, or by bisection (with es4 singled out of course) in a million years when testing all yearly ES versions becomes uneconomical.
Why Is This Update Needed?
One can use the new feature to determine the approximate compatibility of a piece of code. With #72 in place this would make a great tool for devs.
It can also be used for "dating" a piece of ancient code found in some ancient ruins.
