How to extract the user name from an email address using JavaScript?

To extract the user name from an email address using JavaScript, we can use a regex to get the part before the @ with the string match method.

For instance, we write:

const str = "[email protected]";
const nameMatch = str.match(/^([^@]*)@/);
console.log(nameMatch)

to call str.match with /^([^@]*)@/ to get the part of the email address before the @.

Therefore, nameMatch is ['someone@', 'someone', index: 0, input: '[email protected]', groups: undefined].
