[1,2,3].forEach(function(i) {
something();

What is the significance of load factor in HashMap?
...f entries in the map and its load factor should be taken into account when setting its initial capacity, so as to minimize the number of rehash operations. If the initial capacity is greater than the maximum number of entries divided by the load factor, no rehash operations will ever occur.

return !isNaN(parseFloat(n)) && isFinite(n);
}
P.S. isNaN & isFinite...

This will give you today's date in the format of mm/dd/yyyy.
Simply change today = mm +'/'+ dd +'/'+ yyyy; to whatever format you wish.

Error handling in Bash
...foo will be deleted on exit, and the current line number will be printed. (set -e will likewise give you exit-on-error behavior, though it comes with serious caveats and weakens code's predictability and portability).
