var string = "I am the god of hellfire, and I bring you..."

Tests:

slice
var index = Math.floor(Math.random()*17); var substring = string.slice(index, index+8);
substring
var index = Math.floor(Math.random()*17); var substring = string.substring(index, index+8);
substr
var index = Math.floor(Math.random()*17); var substring = string.substr(index, 8);
