After reviewing a chunk of my code for today I continue to admire the flexibility of JavaScript. It’s really powerful. In that example you can get a string split it by a given symbol to an array and than get the Nth element of it. All this on one line! Amazing!

var str = 'my-long-string';
str.split('-')[0]; // will contain "my"

the 1st and 2nd indexes contain respectively “long” and “string”!
