Syntax error on numbers with underscores, such as 1_000_000

[coolaj86]

As with other modern languages, JavaScript numbers may contain _.

Examples:

let population = 8_501_000_000;
let cents = 1_000_000_00;

jshint doesn't seem to be able to parse numbers that use underscores. It fails on the first digit whenever underscores are used:

[jshint] Unexpected '1'. [E]

Thanks for taking the time to file an issue! The language feature you are looking for is called "numeric separators", and if you search this project's issue tracker for that term, you'll find a corresponding feature request. In order to keep things organized, I'm going to close this issue as a duplicate.
