The `apply` function takes three or more arguments, depending on the function being applied to the collection elements.
|
|
|
|
The first argument is the collection itself, the second argument is the function name, and the remaining arguments are passed to the function, with the string `"."` representing the collection element.

```go-html-template
|
|
{{ $s := slice "hello" "world" }}
|
|
|
|
{{ $s = apply $s "strings.FirstUpper" "." }}
|
|
{{ $s }} → [Hello World]
|
|
|
|
{{ $s = apply $s "strings.Replace" "." "l" "_" }}
|
|
{{ $s }} → [He__o Wor_d]
|

```
