What does [[ mean?

[devtrix]

I am very new to Svelte itself and I know that [[...]] in a route is considered as optional argument but in the use-focus action its used as follows,
<InputWrapper label='Name'> <Input use={[[focus]]} bind:value={name} /> </InputWrapper>
Can someone please explain this, [[focus]]? Thanks in advance.

Hi! That's not related to Svelte itself but to the way the define the use prop. The use prop receives an array of actions, and each action entry contains the action and possible arguments for the action. It's better explained in the section Svelte Actions in https://www.svelteui.org/basics

Thank you so much. That makes sense. It would help to take time to read the docs, my bad. This whole Svelte thing is so simple but is so different; thank you for you patient & prompt response. Have a great day/night.
