if

Executes the block if the expression is truthy.

Syntax: if EXPR

The falsy values are false, 0, any nil pointer or interface value, any array, slice, map, or string of length zero, and zero time.Time values.

Everything else is truthy.

{{ $var := "foo" }}
{{ if $var }}
  {{ $var }} → foo
{{ end }}

Use with the else statement:

{{ $var := "foo" }}
{{ if $var }}
  {{ $var }} → foo
{{ else }}
  {{ print "var is falsy" }}
{{ end }}

Use else if to check multiple conditions:

{{ $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 }}
