## Development Helpers

Handlebars and Ember come with a few helpers that can make developing your
templates a bit easier. These helpers make it simple to output variables into
your browser's console, or activate the debugger from your templates.

### Logging

The [`{{log}}`][1] helper makes it easy to output variables or expressions in
 the
current rendering context into your browser's console:

[1]: http://emberjs.com/api/classes/Ember.Templates.helpers.html#method_log

```handlebars
{{log 'Name is:' name}}
```

The `{{log}}` helper also accepts primitive types such as strings or numbers.

### Adding a breakpoint

The [``{{debugger}}``][2] helper provides a handlebars equivalent to JavaScript's
`debugger` keyword.  It will halt execution inside the debugger helper and give
you the ability to inspect the current rendering context:

[2]: http://emberjs.com/api/classes/Ember.Templates.helpers.html#method_debugger

```handlebars
{{debugger}}
```

When using the debugger helper you will have access to a `get` function. This
function retrieves values available in the context of the template.
For example, if you're wondering why a value `{{foo}}` isn't rendering as
expected within a template, you could place a `{{debugger}}` statement and,
when the `debugger;` breakpoint is hit, you can attempt to retrieve this value:

```javascript
> get('foo')
```

`get` is also aware of keywords. So in this situation:

```handlebars
{{#each items as |item|}}
  {{debugger}}
{{/each}}
```

You'll be able to get values from the current item:

```javascript
> get('item.name')
```

You can also access the context of the view to make sure it is the object that
you expect:

```javascript
> context
```
