### Initializing ObjectPath with GitHub Payload in JavaScript

Source: https://github.com/adriank/objectpath.js/blob/master/README.md

This snippet initializes the ObjectPath library by passing the previously defined GitHubPayload object. This creates an ObjectPath instance (op) that can be used to execute queries against the payload.

```javascript
var op=ObjectPath(GitHubPayload)
```

### Defining GitHub Payload Object in JavaScript

Source: https://github.com/adriank/objectpath.js/blob/master/README.md

This snippet defines a sample GitHub webhook payload as a JavaScript object, which serves as the data source for ObjectPath queries. It includes detailed information about the repository, commits, and author details.

```javascript
var GitHubPayload={
  "before": "5aef35982fb2d34e9d9d4502f6ede1072793222d",
  "repository": {
    "url": "http://github.com/defunkt/github",
    "name": "github",
    "description": "You're lookin' at it.",
    "watchers": 5,
    "forks": 2,
    "private": 1,
    "owner": {
      "email": "chris@ozmm.org",
      "name": "defunkt"
    }
  },
  "commits": [
    {
      "id": "41a212ee83ca127e3c8cf465891ab7216a705f59",
      "url": "http://github.com/defunkt/github/commit/41a212ee83ca127e3c8cf465891ab7216a705f59",
      "author": {
        "email": "chris@ozmm.org",
        "name": "Chris Wanstrath"
      },
      "message": "okay i give in",
      "timestamp": "2008-02-15T14:57:17-08:00",
      "added": ["filepath.rb"]
    },
    {
      "id": "de8251ff97ee194a289832576287d6f8ad74e3d0",
      "url": "http://github.com/defunkt/github/commit/de8251ff97ee194a289832576287d6f8ad74e3d0",
      "author": {
        "email": "chris@ozmm.org",
        "name": "Chris Wanstrath"
      },
      "message": "update pricing a tad",
      "timestamp": "2008-02-15T14:36:34-08:00"
    }
  ],
  "after": "de8251ff97ee194a289832576287d6f8ad74e3d0",
  "ref": "refs/heads/master"
}
```

### Querying Commits with Added Files in JavaScript

Source: https://github.com/adriank/objectpath.js/blob/master/README.md

This snippet demonstrates how to find commits that have added files. It uses the `$.commits[@.added is not null]` expression to filter commits where the 'added' property is not null, indicating files were added.

```javascript
//commits that added some files
console.log(op.execute("$.commits[@.added is not null]")
```

--------------------------------

### Querying Commits by Specific Author in JavaScript

Source: https://github.com/adriank/objectpath.js/blob/master/README.md

This snippet demonstrates how to use ObjectPath to find all commits made by 'Chris Wanstrath' within the GitHub payload. It uses the `$.commits[@.author.name is 'Chris Wanstrath']` expression to filter commits based on the author's name.

```javascript
//find all commits by Chris Wanstrath
console.log(op.execute("$.commits[@.author.name is 'Chris Wanstrath']")
```

--------------------------------

### Extracting All Email Addresses in JavaScript

Source: https://github.com/adriank/objectpath.js/blob/master/README.md

This snippet uses ObjectPath to extract all email addresses found anywhere within the GitHub payload. The `$` operator is used for a recursive descent search to find all 'email' properties.

```javascript
//all mails in one list
console.log(op.execute("$..email")
```

--------------------------------

### Deep Scanning for Author Occurrences in JavaScript

Source: https://github.com/adriank/objectpath.js/blob/master/README.md

This snippet shows a deep scan using ObjectPath to find all elements anywhere in the object where the author's name is 'Chris Wanstrath'. The `$` operator performs a recursive descent search.

```javascript
console.log(op.execute("$..*[@.author.name is 'Chris Wanstrath']")
```
