Benchmark: Check first and last char loop charAt startsWith slice regex.test

Script Preparation code:

var pat = "/^http.?:\/\/.+\.com/";
var count = 1000;

Tests:

index
for (var i = 0; i < count; i++) { pat[0] === "/" && pat[pat.length - 1] === "/"; }
charAt
for (var i = 0; i < count; i++) { pat.charAt(0) === "/" && pat.charAt(pat.length - 1) === "/"; }
startsWith & endsWith
for (var i = 0; i < count; i++) { pat.startsWith("/") && pat.endsWith("/"); }
slice
for (var i = 0; i < count; i++) { pat.slice(0, 1) === "/" && pat.slice(-1) === "/"; }
regex test
for (var i = 0; i < count; i++) { (/^\/.+\/$/).test(pat); }
