# Hellrazor.js

Create custom errors for your JavaScript projects

# Installation

1- in browser:

```html

```

2- via NPM:

```

npm install hellrazor

```

# Usage

You'll use `createError()` method to create an error, it takes two strings as parameters for `Error Name` & `Error Message` and will return the new error `Function`

```javascript

// if you have commonjs in your project

// if not skip this line

var Hellrazor = require("hellrazor");

// The below is the same in any JavaScript environment (Browser or Node.js)

var e = Hellrazor.createError("erropac", "use hellrazor 'cause Chrome can't always be your savior");

try {

  // you can re-assign the message if you want

  throw new e("new message");

}

catch (err) {

  console.log(err.name); // erropac

  console.log(err.message); // new message

  console.log(err.stack);

  console.log(err instanceof Error); // true

  console.log(err instanceof e); // true

}

```

### Extra

You can extra objects to the custom error using `prototype`, for example the time when the error occurred

```javascript

var e = Hellrazor.createError("errorName","errorMsg");

try {

  e.prototype.happenAt = new Date();

  throw new e();

}

catch (err) {

  console.log(e.happenAt);

}

```
