How to capitalize one instance of a variable in a live template?

Question

I am trying to make a template for React useState:

const [item, setItem] = useState('value')

const [$state$, set$state$] = useState($init$);$end$

Since item is the same, only with a capital I, is it possible to auto-capitalize the first letter?

I am doing it in VS Code like this:

const [$1, set${1/(.*)/${1:/capitalize}/}] = useState($2)

Answer 1

Create a second variable whose value depends on the first one.

For example, $state_ has its value initialized to capitalize(state) in the edit variables dialog

const [item, setItem] = useState('value')

const [$state$, set$state_$] = useState($init$);$end$
