String split and get first and last occurrences

Question

I have a long string of ISO dates:

var str = \"\'2012-11-10T00:00:00.000Z\', \'2012-11-11T00:00:00.000Z\', ****  \'2013-11-12T00:00:00.000Z\'\";

Answer 1

I have a long string of ISO dates

Assuming these are all using timezone Z, year >= 0 and are spaced and quoted the same way, you don't even have to search for , because they will be of the same length.

var first = str.slice(1, 25),
    last = str.slice(-25, -1);
