Benchmark: string to Uint8Array #5

Script Preparation code:

let repeat_count=5000;
let pattern = 'abcdefgh';
var source = pattern.repeat(5);

Tests:

split + map + instance
const values = source.split('').map(c=>c.charCodeAt()); const res = new Uint8Array(values);
for .. in 1
const values = Array(source.length); for (let i in source) values[i]=source.charCodeAt(i); const res = new Uint8Array(values);
for .. in 2
const values = Array(); for (let i in source) values.push(source.charCodeAt()); const res = new Uint8Array(values);
classical loop
const values = Array(source.length); for (let i =0; i<source.length; i++) values[i]=source.charCodeAt(i); const res = new Uint8Array(values);
classical loop 2
const res = new Uint8Array(source.length); for (let i =0; i<source.length; i++) res[i]=source.charCodeAt(i);
for .. in loop 2
const res = new Uint8Array(source.length); for (let i in source) res[i]=source.charCodeAt(i);
split+forEach
const res = new Uint8Array(source.length); source.split('').forEach( (c,i) => res[i] = source.charCodeAt(i) )
for .. in loop 3
const res = new Uint8Array(source.length); for (let i in source) res[i]=source.charCodeAt(i);
for .. of loop 2
const res = new Uint8Array(source.length); let i=0; for (let c of source) res[i++]=c.charCodeAt();
from
const res = Uint8Array.from(source, c=>c.charCodeAt());
from + split
const res = Uint8Array.from(source.split(''), c=>c.charCodeAt());
TextEncoder
const res = new TextEncoder().encode(source)
