/**
|
|
* Used to test whether a `Maybe` typed value is `null` or `undefined`.
|
|
*
|
|
* When called, the given value's type is narrowed to `NonNullable<T>`.
|
|
*
|
|
* ### Example Usage:
|
|
*
|
|
* ```ts
|
|
* const fn = (str: Maybe<string>) => {
|
|
* if (!isNonNullable(str)) {
|
|
* // typeof str = null | undefined
|
|
* // ...
|
|
* }
|
|
* // typeof str = string
|
|
* // ...
|
|
* }
|
|
* ```
