If I add or delete an element while iterating over an Array or an Array-like object in Javascript, do I need to take into account that the underlying collection may have changed or that the iterators may have become invalidated? In other words, is there an equivalent to the Erase–remove idiom for C++ in Javascript?

There's no equivalent because JS has garbage collection, i.e., you don't need to call
eraseon the tail after calling the equivalent of remove.You can delete from an array while iterating.
