Script Preparation code:
function* createGenerator() { var i; for (i = 0; i < 0; i++) { yield i; } } function createClosure() { var i = 0; return { next() { var result; if (i < 0) { result = { value: i, done: false }; i++; } else { result = { value: undefined, done: true }; } return result; } }; }
Tests:
ES6 generator
var gen = createGenerator(), result; while (!(result = gen.next()).done) { window.result = result.value; }
Closure polyfill
var gen = createClosure(), result; while (!(result = gen.next()).done) { window.result = result.value; }
