Support underscores in numbers

# Alexander Craggs (7 years ago)

Large number are hard to read in JavaScript, is 2384923842 over a billion?  Or just several hundred million.  One solution to this some languages have used is to allow underscores within numbers. You can immediately recognise 2_384_923_842 is a number in the billions, rather than millions.

It would be nice to have such delimiters in large numbers in JavaScript as well, and I don't think it would be breaking.

:-) Just FWIW for future (and lurkers), proposals are listed in the proposals repo (that links to active; also check "inactive" and "finished" which it links to). Also worth searching the mailing list archive and/or esdiscuss.org (which provides a different -- and searchable -- view of the list).
