RuntimeError
external class RuntimeError(val message: String = definedExternally) : <ERROR CLASS> ERROR CLASS: Symbol not found for JsError(source)
Constructs an exception object that is thrown due to an error that can occur at runtime, e.g., out of memory, could not compile shader, etc. If a function may throw this exception, the calling code should be prepared to catch it.
On the other hand, a DeveloperError indicates an exception due to a developer error, e.g., invalid argument, that usually indicates a bug in the calling code.
