How can I Check if a String Matches a Regular Expression in JavaScript?

To check if a string matches a regular expression in JavaScript, you can use the following methods:

Using the test() method:

This method belongs to the RegExp object and returns true if the string matches the regular expression, or false otherwise.

Using the match() method:

This method belongs to the String object and returns an array of matches if the string matches the regular expression. If there is no match, it returns null.

Both methods allow you to check if a string matches a specific pattern defined by the regular expression. Use the one that best fits your use case.
