How to check two string have same characters including special characters

Question

I have two question

1) how can I check two shuffle string have same characters Like I have

var str1 = \"ansar@#//1\";
var str2 = \"@#//sanra1\";
         


        

Answer 1

using a while loop seems a reasonable solution:

var str1 = "ansar@#//1";
var str2 = "@#//sanra12";

s1 = str1.split('');

s2 = str2.split('');


var i = s1.length + 1;
while (i--) {
  if (s2.indexOf(s1[i]) >= 0)
    s2.splice(s2.indexOf(s1[i]), 1);
}

console.log(s2)

the resulting array represents the letters of str2 not matched in str1
