An example merging two maps.
|
|
|
|
```go-html-template
|
|
{{ $default_params := dict "color" "blue" "width" "50%" "height" "25%" }}
|
|
{{ $user_params := dict "color" "red" "extra" (dict "duration" 2) }}
|
|
{{ $params := merge $default_params $user_params }}
|
|
```
|
|
|
|
Resulting __$params__:
|
|
|
|
```
|
|
"color": "red"
|
|
"extra":
|
|
"duration": 2
|
|
"height": "25%"
|
|
"icon": "mail"
|
|
"width": "50%"
|
|
```
|

|
|
Regardless of depth, merging only applies to maps. For slices, use [append]({{< ref "functions/append" >}})
