npm run build
Builds the app for production to thebuildfolder. It correctly bundles React in production mode and optimizes the build for the best performance.
Lifting State Up
When you want to aggregate data from multiple children or to have two child components communicate with each other, move the state upwards so that it lives in the parent component. The parent can then pass the state back down to the children via props, so that the child components are always in sync with each other and with the parent.
