Are the strings anagrams in JavaScript
Anagrams −
Two strings are said to be anagrams of each other if by rearranging, rephrasing or shuffling the first we can form a string identical to the second.
For example −
'something' and 'emosghtin' are anagrams of each other.
We are required to write a JavaScript function that takes in two string, say str1 and str2 and return true if they are anagrams of each other, false otherwise.
Example
The code for this will be −
const str1 = "something";
const str2 = "emosghtin";
const validAnagram = (str1 = '',str2 = '') => {
let obj1 = {}
let obj2 = {}
if (str1.length !== str2.length){
return false
};
for(let char of str1){
obj1[char]= (obj1[char] || 0) + 1
};
for(let char of str2){
obj2[char]= (obj2[char] || 0) + 1
};
for(let val in obj1){
if(!(val in obj2) || (obj2[val] !== obj1[val])){
return false
}
};
return true;
};
console.log(validAnagram(str1, str2));Output
And the output in the console will be −
true
