JavaScript Minification Benchmarks

Re:JavaScript Minification Benchmarks by emptysea on Saturday February 06, 2021 @08:30PM (#26051805)

I think your example should instead be:

    someFunction.toString().charAt(10) == 'a'

so you're getting the function's string representation, not its return value

Also I've never even considered that minifiers can break your code.

To be safe it seems you either need to run minification during test & dev or setup some linting to ban features that could break during minification.

You are totally right, thanks for catching my mistake.

My blog post linked above goes more into the consequences -- ideally you'd formally define what the allowable language subset is.
