I wonder if there's a more elegant, better one-liner to store all values of an iterator rather than a for loop:

// Create a test URLSearchParams object 
var searchParams = new URLSearchParams("key1=value1&key2=value2"); 

// Get all keys
let keys = [];
for(var key of searchParams.keys()) { 
    keys.push(key);
}

    Using spread syntax should work `const keys = [...searchParam.keys()];` – Nick Parsons Feb 05 '20 at 09:27

  • `searchParams.keys()` already returns an array so. just use the returned array as `let keys = searchParams.keys()` – fubar Feb 05 '20 at 09:29

  • @T.J.Crowder I did get the [dupe auto-comment](https://stackoverflow.com/questions/60072674/storing-all-values-of-an-iterator?noredirect=1#comment106244544_60072674). However, since the ratio is 2:1 in votes, the close reason is now "opinion-based". – VLAZ Feb 05 '20 at 09:34

You could use two different methods:

Spead Operator: 

var searchParams = new URLSearchParams("key1=value1&key2=value2"); 
let keys1 = [ ... searchParams.keys() ];
console.log(keys1);

Array.from Spead Operator: 

var searchParams = new URLSearchParams("key1=value1&key2=value2"); 
let keys2 = Array.from(searchParams.keys());
console.log(keys2);
