How to use Symbol iterator Property In Javascript
To make an iterator for an array.
const it = array[Symbol.iterator]();
So, first, we make an iterator for the “array” named “it”. After creating the iterator we iterate to each value stored in that iterator and push it into another array named “p” with the use of the following code
p.push(word)
where the word is the value corresponding to the array of elements stored in the iterator. After iterating through each of the elements we get our final array where all the values of the iterator get stored in p.
Example: In this example, we will convert a JavaScript iterator to a JavaScript Array.
const array = ['Geeks', 'for', 'Geeks'];
let p = []
const it = array[Symbol.iterator]();
console.log(it);
for (let word of it) {
p.push(word)
}
console.log("After the conversion the array becomes");
console.log(p);
Output
Object [Array Iterator] {}
After the conversion the array becomes
[ 'Geeks', 'for', 'Geeks' ]
How to transform a JavaScript iterator into an array ?
