How to extract a substring of a url with regex?

@jerad 

You can use regular expressions to extract a substring of a URL by using the match() method in JavaScript. Here is an example code snippet to extract a substring of a URL using regular expressions:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

const url = "https://www.example.com/page1";
const regex = /(/[w-]+)/?$/; // Regular expression to match the last segment of the URL

const match = url.match(regex);
if (match) {
  const substring = match[1]; // Extracted substring
  console.log(substring);
} else {
  console.log("No match found");
}

In this example, the regular expression (/[w-]+)/?$ is used to match the last segment of the URL (e.g., /page1). The match is then stored in the substring variable, which can be used for further processing.
