Differences in two strings in 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

Example

Let’s say the following are our strings −

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

Example

The code for this will be −

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

The output in the console will be −
