# With Blocks
`{{#with}}` blocks can be used to evaluate an expression and then generate a template block
using the result of the expression.

If not specified, the expression gets assigned to a variable named `item`:

```html
{{#with model.user.post[33].comments[1]}}
<p>{{item.text}}</p>
<p>Posted at: {{item.time}}</p>
{{/with}}
```

To specify the name of the variable inside use `as`, like so:

```html
{{#with comment as model.user.post[33].comments[1]}}
<p>{{comment.text}}</p>
<p>Posted at: {{comment.time}}</p>
{{/with}}
```

The contents of a `{{#with}}` block only render if the expression evaluates to a "truthy" value, and
they can have an optional `{{#else}}` block:

```html
{{#with comment as model.user.post[33].comments[1]}}
<p>{{comment.text}}</p>
<p>Posted at: {{comment.time}}</p>
{{#else}}
<p>No Comment</p>
{{/with}}
```
