Benchmark: replace vs substring vs slice from beginning (+ brackets, substr, compiled vs inline regex)

replace vs substring vs slice from beginning (+ brackets, substr, compiled vs inline regex) (version: 1)

Script Preparation code:

var strIn = '?this=a+test&that=just+it';
var strOut = '';
var regex = /^\?/;

Tests:

substring and substring
strOut = strIn.substring(0,1) === '?' ? strIn.substring(1) : strIn;
replace inline regex
strOut = strIn.replace(/^\?/, '');
replace compiled regex var
strOut = strIn.replace(regex, '');
brackets and substring
strOut = strIn[0] === '?' ? strIn.substring(1) : strIn;
brackets and slice
strOut = strIn[0] === '?' ? strIn.slice(1) : strIn;
substring and slice
strOut = strIn.substring(0,1) === '?' ? strIn.slice(1) : strIn;
brackets and substr (legacy)
strOut = strIn[0] === '?' ? strIn.substr(1) : strIn;
substr and substr (legacy)
strOut = strIn.substr(0,1) === '?' ? strIn.substr(1) : strIn;
