Validating Email Addresses Using JavaScript Regex

As a beginner to regex, I am just trying to validate if ([email protected]) works correctly. This is what I have attempted so far.

var checkEmail = /^\w+@\w+\.[a-zA-Z]/;

Is the above regex pattern suitable for my validation needs?

Answer №1

If you want to improve on what you currently have:

var checkEmail = /^\w+@\w+\.[a-zA-Z]+/;

Your initial attempt is almost there (just remember to escape the . so it doesn't match any character and add a + after the [a-zA-Z] since top-level domains are typically at least 2 characters long), but for something as complex as an email address which has a detailed specification, it might be better to use a regex pattern from a reliable source.

Answer №2

It's important to remember to escape the dot in your regex patterns, as it is a meta character that can match anything. Here's an example:

/^\w+@\w+\.[a-zA-Z]/
