When used with a numeric INDEX, it queries positional parameters (starting with 0). With a string KEY, it queries named parameters. 23 24 When accessing a named parameter that does not exist, `.Get` returns an empty string instead of interrupting the build. The same goes with positional parameters in hugo version 0.40 and after. This allows you to chain `.Get` with `if`, `with`, `default` or `cond` to check for parameter existence. For example, you may now use: 25 26 ``` 27 {{ $quality := default "100" (.Get 1) }} 28 ``` 29 30 [sc]: /templates/shortcode-templates/
