...s trick will work (for example) in Java, Perl, .NET and JGSoft, but not in PHP (PCRE), Ruby 1.9+ or TextMate (both Oniguruma). JavaScript's /y (sticky flag) isn't as flexible as \G, and couldn't be used this way even if JS did support lookbehind.

Create an array with same element repeated multiple times
...
It's much more efficient to allocate all of the entries up front, with arr = new Array(len);, then assign to them by index in the loop, i.e. arr[i] = value;. That way you only pay O(n) rather than having to keep reallocating the array as it grows. In ...
