Tests:

Blob

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

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

TextEncoder

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

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