Benchmark: normalize / trim text

Script Preparation code:

function makeid(length) {
    let result = '';
    const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 ';
    const charactersLength = characters.length;
    let counter = 0;
    while (counter < length) {
      result += characters.charAt(Math.floor(Math.random() * charactersLength));
      counter += 1;
    }
    return result;
}

var data = Array(10000).fill(Array(40).fill(makeid(1000)))   
var rows = []
var row = {}

Tests:

no
data.forEach((items) => {items.forEach((item,i)=>{row[i] = item}); rows.push(row)})
normalize
data.forEach((items) => {items.forEach((item,i)=>{row[i] = item.normalize()}); rows.push(row)})
trim
data.forEach((items) => {items.forEach((item,i)=>{row[i] = item.trim()}); rows.push(row)})
both 1
data.forEach((items) => {items.forEach((item,i)=>{row[i] = item.normalize().trim()}); rows.push(row)})
both 2
data.forEach((items) => {items.forEach((item,i)=>{row[i] = item.trim().normalize()}); rows.push(row)})
