It is a bad practice to throw something that’s not derived at some level from Error. If you can’t find an existing
Error type that suitably conveys what you need to convey, then you should extend Error to create one.
Specifically, part of the point of throwing Errors is to communicate about the conditions of the error, but literals have far less
ability to communicate meaningfully than Errors because they don’t include stacktraces.
Noncompliant Code Example
throw 404; // Noncompliant
throw "Invalid negative index."; // Noncompliant
Compliant Solution
throw new Error("Status: " + 404);
throw new Error("Invalid negative index.");{code}
