Check Whether Two Strings are Anagram of each other or not.

 Anagram of two strings means that contains the same characters and the repeating characters are same in the two strings but order of the characters may be different.

Example-  "blog" and "logb" ; this two strings are Anagram.

Code in JavaScript :

//Check two strings are anagram or not

//input string : 'hello' and 'llheo'

//first check the length.

//count the alphabate like this {h:1,e:1,l:2,o:1}

//check the each alphabate and decrease by the value by 1

//IF ALL VALUES ARE ZERO THEN ANAGRAM IS TRUE, otherwise false

function isAnagram(string1,string2){

if(string1.length!==string2.length){

    return false;

}

let counter={}

for(let letter of string1){

    counter[letter]=(counter[letter] || 0) + 1;

}

    console.log(counter);

for(let items of string2){

    if(!counter[items]){

        return false;

    }

    counter[items]-=1

}

return true;

}

const check=isAnagram('Anagram','gramnAa')

console.log(check);
