+`wrapNullable` didn't account for an undefined input and would result in a return value of `some(undefined)` causing `isNone` checks to not pass if `undefined` was the `nullable` value.
+
+```ts
+export const wrapNullable = <T>(nullable: Nullable<T>): Option<T> =>
+  nullable !== null ? some(nullable) : none<T>();
+```
+
+Added a `wrapNullish` function to check for both `null` and undefined which will return the value of `none()` if `null` or `undefined` is the presented `nullish` value.
+
+```ts
+export const wrapNullish = <T>(nullish: Nullish<T>): Option<T> =>
+  nullish !== null && nullish !== undefined ? some(nullish) : none<T>();
+```
+
+- `Nullish` type added.
+- `wrapNullish` function added.
+- Tests for `wrapNullish` added.
