Find the dissimilarities in two strings - JavaScript

We are required to write a JavaScript function that takes in two strings and find the number of corresponding dissimilarities in the strings

The corresponding elements will be dissimilar if they are not equal. Let’s say the following are our two string −

const str1 = 'Hello world!!!';
const str2 = 'Hellp world111';

Example

Following is the code −

const str1 = 'Hello world!!!';
const str2 = 'Hellp world111';
const dissimilarity = (str1 = '', str2 = '') => {
   let count = 0;
   for(let i = 0; i < str1.length; i++){
      if(str1[i] === str2[i]){
         continue;
      };
      count++;
   };
   return count;
};
console.log(dissimilarity(str1, str2));

Output

Following is the output in the console −
