How to transform a JavaScript iterator into an array?

  • Last Updated : 11 Aug, 2021

The task is to convert an iterator into an array

This can be performed by iterating each value of the iterator and storing the value into another array 

Method: 

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 in another array named “p” with the use of the following code



p.push(word) 

where the word is the value corresponding to the array elements stored in the iterator. After iterating through each of the element we get our final array where all the values of the iterator get stored in p.

Example:  

javascript




<script>
    const array = ['Geeks', 'for', 'Geeks'];
    p=[]
    const it = array[Symbol.iterator]();
    document.write(it);
    document.write("<br>");
 
    for(let word of it)
    {
       p.push(word)
    }
document.write(
"After the conversion the array becomes");
document.write("<br>");
document.write(p);
</script>

Output:

[object Array Iterator]
After the conversion the array becomes
["Geeks", "for", "Geeks"]
