To check what the real type of and variable, run this command:

  Object.prototype.toString.call(myVar)

It'll return something like [object Object]. The second word is the real type of the variable.

Some examples:

fmartins-andre

You could define a ref, and then inside the object, make multiple subvalues based on the key of the child:

const ref = useRef({})

{array.map((item)=><div key={item.id} ref={ref.current[item.id] ??= { current: null }}>{item.id}</div>)}

Another approach is callback refs:

#!/bin/bash

lightMode="'prefer-light'"
darkMode="'prefer-dark'"

ligthTheme="'Adwaita'"
darkTheme="'Adwaita-dark'"


function toggleMode {

#!/bin/bash

echo 'Removing origins...'
git remote prune origin

BRANCHES=`git branch -vv | grep 'origin/.*: gone]' | awk '{print $1}'`

if [[ `echo -e "$BRANCHES" | wc -w` -gt 0 ]]; then
        echo 'Removing branches:'
        echo $BRANCHES
