Specification
https://tc39.es/proposal-iterator-join


Summary
A TC39 proposal to add to JavaScript a means to concatenate the contents of an 
iterator into a string. The `join()` method of Iterator instances is similar to 
`Array.prototype.join()`: it returns a string that is the concatenation of all 
elements produced by the iterator, separated by commas or a specified separator 
string.
