It is a bad practice to <code>throw</code> something that's not derived at some level from <code>Error</code>. If you can't find an existing <code>Error</code> type that suitably conveys what you need to convey, then you should extend <code>Error</code> to create one.
|

|
|
|
||
|
|
Specifically, part of the point of throwing \<code>Error</code>s is to communicate about the conditions of the error, but literals have far less ability to communicate meaningfully than \<code>Error</code>s 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}
