Masking email to hide it in JavaScript
It is a common practice that when websites display anyone's private email address they often mask it in order to maintain privacy.
Therefore for example −
If someone's email address is −
const email = 'ramkumar@example.com';
Then it is displayed like this −
const masked = 'r...r@example.com';
We are required to write a JavaScript function that takes in an email string and returns the masked email for that string.
Example
Following is the code −
const email = 'ramkumar@example.com'; const maskEmail = (email = '') => { const [name, domain] = email.split('@'); const { length: len } = name; const maskedName = name[0] + '...' + name[len - 1]; const maskedEmail = maskedName + '@' + domain; return maskedEmail; }; console.log(maskEmail(email));
Output
Following is the output on console −
r...r@example.com
