 5. The way this works is that VS Code will scrape the output which is set to the console. If a line 
     matches the pattern, it will launch a browser against the URL which was 'captured' by the pattern.
     Here is an explanation of what the pattern does:
-    * `^`: This indicates that the pattern should only be matched against the beginning of a line.
-    * `\\s*` : Matches zero or more whitespace characters. Note that `\s` indicates a whitespace character, but because this is in a json string, the `\` needs to be escaped, hence `\\s`.
+    * `\\b` : Matches on a word boundery. Note that `\b` indicates a word boundary, but because this is in a json string, the `\` needs to be escaped, hence `\\b`.
     * `Now listening on:` : This is a string literal, meaning that the next text must be `Now listening on:`.
     * `\\s+` : Matches one or more space characters.
     * `(` : This is the beginning of a 'capture group' -- this indicates which region of text will be saved and used to launch the browser.
