Access the previous value of a variable with this React hook
npm install @rooks/use-previous``
npm install rooks
or
`
yarn add rooks
Rooks is completely treeshakeable and if you use only 1 of the 50+ hooks in the package, only that hook will be bundled with your code. Your bundle will only contain the hooks that you need. Cheers!
