Benchmark: Compare TextEncoder, Blob, new TextEncoder

Script Preparation code:

iterations = 1000;
function randomStringGen(n) {
    let strings = [];
    for (let i = 0; i < n; i++) {
      let s = Math.random().toString(36).substring(2, 15) + Math.random().toString(36).substring(2, 15);
      strings[i] = s;
    }
    return strings;
}
var randomStrings = randomStringGen(iterations);
var encoder = new TextEncoder();

Tests:

TextEncoder
var j = 0; for (let i = 0; i < iterations; i++) { var str = randomStrings[i % iterations]; console.log(encoder.encode(str).length) }
Blob
var j = 0; for (let i = 0; i < iterations; i++) { var str = randomStrings[i % iterations]; console.log(new Blob([str]).size) }
TextEncoder new
var j = 0; for (let i = 0; i < iterations; i++) { var str = randomStrings[i % iterations]; console.log(new TextEncoder().encode(str).length) }
