Question

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

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


        

Answer 1

Consider these implementations:

1)

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

function first(str1, str2) {
    return Array.prototype.every.call(str1, function(c) {
        return str2.indexOf(c) > -1;
    }, this);
}

console.log(first(str1, str2));

var str1 = "ansar@#//123";
var str2 = "@#//sanra";

function second() {
    return Array.prototype.filter.call(str1, function(c) {
        return str2.indexOf(c) === -1;
    }, this).join('');
}

console.log(second(str1, str2));

Update for checking if strings contain same characters you can use ES6 Set:

const checkIfStringsContainSameCharacters = (string1, string2) => {
  return new Set(string1).size === new Set(string1 + string2).size;
}
