```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 }}
|
|
```
