> check if a string is a valid ECMAscript identifier

All the code is based on [this repo](https://github.com/mathiasbynens/mothereff.in/tree/master/js-variables), I am just putting it into npm.

## Installation

```bash
npm install --save is-valid-identifier
```

## Usage

```javascript
const isValidIdentifier = require('is-valid-identifier')

isValidIdentifier('404') // => false
isValidIdentifier('404', true) // => second argument is for strict mode, instead of returning a false, will throw an exception
```
