How to properly validate an email in JavaScript using regular expressions?

Hello everyone! I'm a beginner in JavaScript and I'm writing a registration form for a website. I need to check that the user entered a valid email before sending the data to the server. I wrote this function: ```javascript function validateEmail(email) { if (email.includes('@') && email.includes('.')) { return true; } else { return false; } } ``` But it allows clearly invalid addresses, for example: "test@.com" or "user@domain" (without a dot). I understand that I need to use regular expressions, but I don't know much about them. I tried copying something like `/^\S+@\S+\.\S+$/` from the internet, but it also doesn't work for all cases — for example, it allows "a@b.c" (which seems valid, but I'm not sure). Please advise how to write a reliable email validation.
