Benchmark: forEach vs For of and startsWith - MeasureThat.net

Script Preparation code:

const strs = [
    '',
    '*',
    '#',
    '*short',
    '#short',
    '*'.padEnd(2500, '-'),
    '#'.padEnd(2500, '-'),
];

Tests:

.startsWith forEach
strs.forEach(str => {str.startsWith('*')})
.charAt forEach
strs.forEach(str => {str.charAt(0) === '*'})
[0] forEach
strs.forEach(str => {str[0] === '*'})
.match forEach
strs.forEach(str => {str.match(/^\*/)})
.startsWith
for(const str of strs) {str.startsWith('*')}
.charAt
for(const str of strs) {str.charAt(0) === '*'}
[0]
for(const str of strs) {str[0] === '*'}
.match
for(const str of strs) {str.match(/^\*/)}
