Benchmark: slice vs substring performance

Script Preparation code:

var str = '<div>AAA A<p style="text-align: center;"><b><span style="font-family: "times new roman"; font-size: 12pt;"></span><span style="font-family: "times new roman"; font-size: 12pt; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);">AAA A</span></b><span style="font-family: "times new roman"; font-size: 12pt;"></span></p></div>';

Tests:

slice
var str1 = str.slice(20,50)
substring
var str1 = str.substring(20,50)
