Methods

catch

▸ catch<TResult>(onrejected?): Promise<T | TResult>

Attaches a callback for only the rejection of the Promise.

Type parameters

Name	Type
`TResult`	`never`

Parameters

Name	Type	Description
`onrejected?`	`null` \| (`reason`: `any`) => `TResult` \| `PromiseLike`<`TResult`>	The callback to execute when the Promise is rejected.

Returns

Promise<T | TResult>

A Promise for the completion of the callback.

Inherited from

Promise.catch

finally

▸ finally(onfinally?): Promise<T>
