`Array.prototype.find` returns the element from an array, and `Array.prototype.reduce` allows you to map to antother value. `reduceFirst` combines these to return a transformation of the first item that returns a value.

## Installation

```sh
yarn add reduce-first
```

```sh
npm install reduce-first
```

```sh
pnpm add reduce-first
```

## Usage

```ts
import reduceFirst from "reduce-first";

const list = ["a", "b", "c", "d", "e"];

const result1 = reduceFirst(list, (value, index, arr) => {
  if(value === "c") {
    return `found ${value}`;
  }
});
// result1 === "found c"

const result2 = reduceFirst(list, (value, index, arr) => {
  if(value === "x") {
    return `found ${value}`;
  }
});
// result2 === undefined
```
