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

Use with the [`else`] statement:

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

Use `else if` to check multiple conditions:

```go-html-template
{{ $var := 12 }}
{{ if eq $var 6 }}
  {{ print "var is 6" }}
{{ else if eq $var 7 }}
  {{ print "var is 7" }}
{{ else if eq $var 42 }}
  {{ print "var is 42" }}
{{ else }}
  {{ print "var is something else" }}
{{ end }}
```
