I need to hide parts of a string using javascript, I have the email:
[email protected]
And I need to transform into:
hi****@email.com
And I need to display the email after the @, but I don't know how to do this.

A RegExp might be good. Regex Editor.
Leaving the first two letters and replacing the rest before the @ to be replaced
let str = '[email protected]';
console.log(str.replace(/(\w{2}).*?@/, '$1****@'));

This is good because it replaces the remaining letters with four asterisks as requested, not "however many remaining letters there were" asterisks.
Here's a quick way using map() and repeat()
let email = "[email protected]";
const obfuscate = str => str.split('@').map((e, i) => i === 0 ? e.slice(0, 2) + '*'.repeat(e.length - 2) : e).join('@');
console.log(obfuscate(email))

'*'.repeat(e.length - 2) is probably not ideal from a privacy POV; perhaps a hardcoded value would be better.First get your index of @ With
Var ind =str.indexof("@")
then loop from index 2 to ind and each loop replace this char with *

I feel this could be achieved using indexOf() and a for loop.
let email = '[email protected]';
let atPosition = email.indexOf('@'); //get @ position
let startIndex = atPosition > 2 ? 2: 0; //handle case for really small email names
if(atPosition > -1){
for(let i = startIndex ; i < atPosition;i++){
email = email.substring(0, i) + '*' + email.substring(i + 1);
}
}
console.log(email);Using the .subtstring() method to replace a character in a string.
email[i] = '*' will not work, strings are immmutable.

You can use the below code to achieve what you need.
const str = '[email protected]';
const [contact, domain] = str.split('@');
const maskedMailId = contact.slice(0, 2) + '*'.repeat(contact.length - 2) + '@' + domain;
console.log(maskedMailId);
