Benchmark: Generator vs. POJO with `next()` method

Script Preparation code:

var str = ""

for (let i = 0; i < 100; i++) {
  str += " save my home in the jungle save my home in the polar save my home in the ocean save my home in the desert "
}

Tests:

POJO
function createCharStream(input) { let index = 0 return { next() { return input.charAt(index++) } } } const chars = createCharStream(str) let strCopy = "" for (let char; (char = chars.next()) !== "";) { strCopy += char }
generator
function* createCharStream(input) { let index = 0 while (index < input.length) { yield input.charAt(index++) } } const chars = createCharStream(str) let strCopy = "" for (const char of chars) { strCopy += char }
