How to validate Email Address using Regular expression in Typescript?

 In TypeScript, you can use regular expressions (also known as regex or regexp) to validate email addresses. Here's an example of how you can do email validation using regular expression in TypeScript:

typescript
const emailRegex = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;

function validateEmail(email: string): boolean {
  return emailRegex.test(email);
}

// Example usage
console.log(validateEmail("test@example.com")); // Output: true
console.log(validateEmail("invalid-email@")); // Output: false

In the example above, the regular expression emailRegex matches any string that contains:

• One or more characters from the set [a-zA-Z0-9._%+-], which includes letters, digits, and some special characters commonly used in email addresses.
• The @ symbol.
• One or more characters from the set [a-zA-Z0-9.-], which includes letters, digits, and some special characters commonly used in domain names.
• A period ..
• Two or more characters from the set [a-zA-Z], which includes letters.

The validateEmail function takes an email address as input and returns true if the email address matches the regular expression, and false otherwise.

Note that this regular expression may not match all possible valid email addresses, as the rules for email addresses can be complex and vary depending on the email service provider. However, it should cover most common cases.
