As mentioned on Discord earlier, we'll add these to all new functions going forward - this is the backfill. Reasons: - It makes you look at the spec, implementing based on MDN or V8 behavior is a no-go - It makes finding the various functions that are non-compliant easier, in the future everything should either have such a comment or, if it's not from the spec at all, a comment explaining why that is the case - It makes it easier to check whether a certain abstract operation is implemented in LibJS, not all of them use the same name as the spec. E.g. RejectPromise() is Promise::reject() - It makes it easier to reason about vm.arguments(), e.g. when the function has a rest parameter - It makes it easier to see whether a certain function is from a proposal or Annex B Also: - Add arguments to all functions and abstract operations that already had a comment - Fix some outdated section numbers - Replace some ecma-international.org URLs with tc39.es
