How to convert all elements in an array to integer in JavaScript?

Question

I am getting an array after some manipulation. I need to convert all array values as integers.

My sample code

var result_string = \'         


        

Answer 1

ECMAScript5 provides a map method for Arrays, applying a function to all elements of an array. Here is an example:

var a = ['1','2','3']
var result = a.map(function (x) { 
  return parseInt(x, 10); 
});

console.log(result);
