An error message helps you to find out what's the cause of the problem. So the goal of error messages is making debugging easier and faster.

For example..

try {
    adddlert("Welcome!");
}
catch(err) {
    console.log(err.message);
}

In this example you see immediately in the console that you typed the function "alert" wrong. This could save a lot of time because you don't have to search through the hole project to find cause of the problem.

This is a very simple example but i hope understand what i'm trying to say.
