## Install
```
$ npm install help-is
```
## Import

This package is pure [ESM](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules). It cannot be `require()`'d from CommonJS.

Use `import foo from 'foo'` instead of `const foo = require('foo')` to import the package.

```js
// Load entire build
import is from 'help-is';
```
If the package is used in an async context, you could use [`await import(…)`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import#dynamic_imports) from CommonJS instead of `require(…)`.

**You also need to make sure you're on the latest minor version of Node.js. At minimum Node.js 12.20, 14.14, or 16.0.**
