## Usage

[![Undercut Demo](https://codesandbox.io/static/img/play-codesandbox.svg)](https://codesandbox.io/s/undercut-demo-1up46?fontsize=14&hidenavigation=1&moduleview=1&theme=dark&previewwindow=console&file=/utils.js)

```js
import { isNumberValue } from "@undercut/utils";

console.log(isNumberValue(123)); // true
console.log(isNumberValue("hello")); // false
console.log(isNumberValue(NaN)); // false
```

## Prerequisites

The package is compliant with the [Raw Module Specification 0.3.0](https://github.com/the-spyke/rms) and provides original modern JavaScript code in the `ESM` format.

You may need to compile the code and/or load polyfills depending on your environment. Look for exact minimum versions of `@babel/preset-env` and `core-js` in the `package.json`.

Most modern apps already have such infrastructure or use similar tools. So most likely you don't have to do anything. If not, just add [Babel](https://babeljs.io/setup) to your build step.

## Installation

```sh
npm install @undercut/utils
# or
yarn add @undercut/utils
```

## Updating

As descibed in [RMS](https://github.com/the-spyke/rms): in case of upgrading the package to a newer version, please do so for `@babel/preset-env` and `core-js` too.
