```go-html-template
{{ $var := "foo" }}
{{ with $var }}
  {{ . }} → foo
{{ end }}
```

Use with the [`else`] statement:

```go-html-template
{{ $var := "foo" }}
{{ with $var }}
  {{ . }} → foo
{{ else }}
  {{ print "var is falsy" }}
{{ end }}
```

Initialize a variable, scoped to the current block:

```go-html-template
{{ with $var := 42 }}
  {{ . }} → 42
  {{ $var }} → 42
{{ end }}
{{ $var }} → undefined
```

## Understanding context

At the top of a page template, the [context] (the dot) is a `Page` object. Inside of the `with` block, the context is bound to the value passed to the `with` statement.

With this contrived example:

```go-html-template
{{ with 42 }}
  {{ .Title }}
{{ end }}
```

Hugo will throw an error:

    can't evaluate field Title in type int

The error occurs because we are trying to use the `.Title` method on an integer instead of a `Page` object. Inside of the `with` block, if we want to render the page title, we need to get the context passed into the template.

{{% note %}}
Use the `$` to get the context passed into the template.
{{% /note %}}

This template will render the page title as desired:

```go-html-template
{{ with 42 }}
  {{ $.Title }}
{{ end }}
```

Gaining a thorough understanding of context is critical for anyone writing template code.
