Is it right way to use useWatch hook conditionally ?

[abdulmateentechbits]

Here I am using useWatch hook conditionally like bellow for an array value (cr_heads)

const crHeadArray = useWatch({ control, name: 'cr_heads' }) || [];

Why I am using it conditionally?

It's because of when useWatch can not watch that value has change it return undefined it cause and error when I use forEach loop over crHeadArray.
That's why I am using useWatch conditional if useWatch can not see any changes rather then return undefined it will return empty array so there were no issue in forEach loop

no, that's a rule of react custom hook. you can use the disbaled prop to pause the subscription.
