Benchmark: Count string without space

Script Preparation code:

var str = 'ABCD EFG HIJKLMN OP QR STU V W XYZ';
var strLength = str.length;
var matchCountRegExp = /\S/g;
var replacedTextRegExp = /\s/g;

Tests:

Regex match count
str.match(matchCountRegExp).length;
Get replaced text length with regex
str.replace(replacedTextRegExp, '').length;
Get replaced text length with String.replaceAll()
str.replaceAll(' ', '').length;
Get replaced text length with String.split()
str.split(' ').join('').length;
Calculate with String.split()
str.length - str.split(' ').length + 1;
Calculate in simple for loop
let count = 0; for (let i=0; i < strLength; i++) { if (str[i] !== ' ') count++ }
