JavaScript: Rearrange characters of a given string in such way that it will become equal to another given string

JavaScript Basic: Exercise-99 with Solution

Write a JavaScript program to check whether it is possible to rearrange characters of a given string in such way that it will become equal to another given string.

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title> Rearrange characters of a given string in such way that it will become equal to another given string</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function rearrangement_characters(str1, str2) {

  var first_set = str1.split(''),
      second_set = str2.split(''),
      result = true;

  first_set.sort();
  second_set.sort();

  for (var i = 0; i < Math.max(first_set.length, second_set.length); i++) {
    if (first_set[i] !== second_set[i]) {
      result = false;
    }
  }

  return result;
}

console.log(rearrangement_characters("xyz", "zyx"))
console.log(rearrangement_characters("xyz", "zyp"))

Sample Output:

true
false

Previous: Write a JavaScript program to switch case of the minimum possible number of letters to make a given string written in the upper case or in the lower case.
Next: Write a JavaScript program to check if there is at least one element which occurs in two given sorted arrays of integers.

JavaScript: Tips of the Day

Classes/function constructors

class Person {
  constructor() {
    this.name = 'Owen';
  }
}

Person = class AnotherPerson {
  constructor() {
    this.name = 'Eddie';
  }
};

const member = new Person();
console.log(member.name);

We can set classes equal to other classes/function constructors. In this case, we set Person equal to AnotherPerson. The name on this constructor is Eddie, so the name property on the new Person instance member is "Eddie".
