Benchmark: time complexity - MeasureThat.net

Script Preparation code:

const s = "He is a very very good boy, isn't he?"
const specialChar = ['!', '?', ',', '.', '_', '@'];
const specialCharSet = new Set(specialChar);

Tests:

set.has
const setFunct = (s) => { let ArrOfChar = s.split(''); const ArrWithoutSpecialChar = []; for (let i = 0; i < ArrOfChar.length; i++) { if (!specialCharSet.has(ArrOfChar[i])) { if (ArrOfChar[i] === "'") ArrOfChar[i] = ' '; ArrWithoutSpecialChar.push(ArrOfChar[i]); } } let cleanArr = ArrWithoutSpecialChar.join('').split(' '); console.log(cleanArr.length); cleanArr.forEach((token) => console.log(token)); };
Array.includes
const arrFunct = (s) => { let ArrOfChar = s.split(''); const ArrWithoutSpecialChar = []; for (let i = 0; i < ArrOfChar.length; i++) { if (!specialChar.includes(ArrOfChar[i])) { if (ArrOfChar[i] === "'") ArrOfChar[i] = ' '; ArrWithoutSpecialChar.push(ArrOfChar[i]); } } let cleanArr = ArrWithoutSpecialChar.join('').split(' '); console.log(cleanArr.length); cleanArr.forEach((token) => console.log(token)); };
