If i have 'var' how can i get "e,o,o" out of it ?
With substring you can only get the position

var str = "Hello world!";

var res = str.substring(1, 4);

It's not entirely clear if you only want the vowels or if you want all except the vowels. Either way, a simple regular expression can get the characters you need.

let str = Hello World;



let res = str.match(/[aeiou]/ig).join();

console.log(res);



let res2 = str.match(/[^aeiou]/ig).join();

console.log(res2);

Remove the .join("") part if you want an array, otherwise this gives you a string
