## @jakxz/functional-or



### functionalOr(...fns) ⇒ function ⏏

A utility for composing a set of predicate functions that check against the

curried data to find if one of the predicate conditions is met. This is most

helpful when your predicates are relatively complex and you want to compose

the checks in existing piped or composed functions; for the simplest example,

if you have:

```js

const isFoo = (str) => str === "foo";

const isBar = (str) => str === "bar";

```

you can compose these functions into:

```js

import or from "@jakxz/functional-or";

const isFooOrBar = or(isFoo, isBar);

```

and use it like so:

```js

const results = ["foo", "bar", "baz"].filter(isFooOrBar);

```

If you don't want to pass any functions at all, you can just check the truthyness

of your data args:

```js

const isAnyTruthy = or()("x", "y", 0, null);

```
