|
> Check if something is a promise
|
|
|
|
Why not [`is-promise`](https://github.com/then/is-promise)? That module [checks for a thenable](https://github.com/then/is-promise/issues/6), not an ES2015 promise. This one is stricter.
|
|
|
|
You most likely don't need this. Just pass your value to `Promise.resolve()` and let it handle it.
|
|
|
|
Can be useful if you need to create a fast path for a synchronous operation.
