Benchmark: string characters split map vs for loop vs split foreach

Tests:

split map
const string = 'asdf1234qwer'; const mapper = (char) => String.fromCharCode(char.charCodeAt(0)) string.split('').map(mapper).join('')
for loop
const string = 'asdf1234qwer'; const mapper = (char) => String.fromCharCode(char.charCodeAt(0)) let result = "" for(const char of string) { result += mapper(char) }
split foreach
const string = 'asdf1234qwer'; const mapper = (char) => String.fromCharCode(char.charCodeAt(0)) let result = '' string.split('').forEach(char => { result += mapper(char) })
