Regular Expression
This approach involves defining a regular expression pattern that matches valid email formats. We can then use the test() method of the regular expression object to check if an input string matches the pattern.
Syntax:
const emailPattern = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;
const isValid = emailPattern.test(email);
Javascript
const email = "nikhil@gmail.com"; const emailPattern = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/; const isValid = emailPattern.test(email); console.log(isValid); |
Output
true
