An ESnext spec-compliant `Number.isInteger` shim/polyfill/replacement that works as far down as ES3.

This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the [spec](https://tc39.es/ecma262/#sec-number.isinteger).

## Getting started

```sh
npm install --save number.isinteger
```

## Usage/Examples

```js
console.log(Number.isInteger(-3)); // true
console.log(Number.isInteger(2 ** 54)); // true
console.log(Number.isInteger(2.3)); // false
console.log(Number.isInteger(Infinity)); // false
console.log(Number.isInteger("7")); // false
```

## Tests

Clone the repo, `npm install`, and run `npm test`
