type CustomErrorConstructor<T extends CustomError = CustomError> =
new (message?: string) => T
interface SerializableError {

ancestors: string[]
}
class CustomError extends Error {}
CustomError
has better default behaviors than Error
:
console.error
prints the correct exception name, not Error
.instanceof
operator matches based on names rather than inheritance relationships, which helps SerializableError instanceof CustomError
.class AssertionError extends CustomError {}
function isError(val: unknown): val is Error
function isntError<T>(val: T): val is Exclude<T, Error>
function normalize(err: Error): SerializableError
function hydrate(err: SerializableError): Error
function isSerializableError(val: unknown): val is SerializableError
/**
* @throws {AssertionError}
*/
function assert(condition: unknown, message?: string): asserts condition
function getErrorNames(err: Error | SerializableError): Iterable<string>
function traverseErrorPrototypeChain(err: Error): Iterable<Error>
