Another reason to use `void 0` is that "void 0" takes only 6 characters while "undefined" takes 9, saving some bandwidth. It is common practice for JavaScript minifiers to use this substitution.

Given it will be gzip-compressed in transport, does this really save a meaningful amount of bandwidth?

It’s really more that there is no reason not to do it. Void is marginally safer as well as shorter, so any minifier/transpile step etc will make this substitution.
