How to use a for…of Loop In Javascript
To transform a JavaScript iterator into an array using a for…of loop, initialize an empty array, then iterate over the iterator with the loop, pushing each value into the array. This method is straightforward and compatible with all iterable objects.
Example: In this example we defines a generator function that yields numbers 1, 2, and 3. It creates an iterator from the generator and transforms it into an array using a loop. Finally, it logs the array.
function* generateNumbers() {
yield 1;
yield 2;
yield 3;
}
const iterator = generateNumbers();
const array = [];
for (const value of iterator) {
array.push(value);
}
console.log(array);
Output
[ 1, 2, 3 ]
