Hi can anyone help me with this syntax

const errorMessage = `There was an error getting the profile of ${username} (${response.statusCode})

I understand ${username} but the next one is confusing to me. Why does it have parenthesis around the variable ${response.statusCode} ?

It's just to make it readable, you could enclose the ${response.statusCode} in whatever you wanted inside your template string.

const errorMessage = `There was an error getting the profile of ${username} (${response.statusCode})`;
// will return something like "There was an error getting the profile of Clark Kent (400)";

const errorMessage = `There was an error getting the profile of ${username} --- ${response.statusCode} --- `;
// will return something like "There was an error getting the profile of Clark Kent --- 400 ---";
