Count number of occurrences for each char in a string

Question

I want to count the number of occurrences of each character in a given string using JavaScript.

For example:

var str = \"I want to count the number         


        

Answer 1

This worked well for me :

    function Char_Count(str1) {
    var chars = {};
    str1.replace(/\S/g, function(l){chars[l] = (isNaN(chars[l]) ? 1 : 
    chars[l] + 1);});
    return chars;
  }

  var myString = "This is my String";
  console.log(Char_Count(myString));
