Answer 1

 var ns =['Kyle', 'Mods',1,2,3]; ns.forEach((element) => { if(!isNaN(element)) { console.log(element) } }) 

Checkfor each element is number or not

Answer 2

Try as follows

  var ns =['Kyle', 'Mods',1,2,3]; ns.forEach(function(ele){ if (Number.isInteger(ele)) console.log(ele); }) 

Answer 3

try this

var ns =['Kyle', 'Mods',1,2,3];

console.log(ns.filter(x=> !isNaN(x) ));

Answer 4

ES6 Destructuring Assignment

var ns =['Kyle', 'Mods',1,2,3];
var [ , , ...numbers] = ns;
console.log(numbers);

And the ... is Spread Syntax .
