For this discussion, we took a look at how props and state can work within ReactJS. When it comes to state versus props, according to Faizan, $$State refers to the internal data of a component that can change over time, while props are used to pass data between components$(2023).$ Which is why dynamic, interactive web applications, state and props are both important as they play key roles in managing different data and interactivity.

A great example that was used in the instructions is an e$-$commerce website $($like Under Armour or NFL Shop$).$ Within the website that uses a $$shopping cart$,$ state is used to track the data of what is in the cart, the data shows the amount of what is in the cart. While props work to pass the data of what the item in the cart is $($like descriptions$).$

Now with the amount of inventory never being a guaranteed number and always changing, state is used. So$,$ when an item is moved to a cart, the real time information is changed through state so that a customer does not have an $$out$-$of$-$stock$$ item in their cart that they could purchase. With the live data updated by the state, the props are able to let the child components update different aspects $($could be disabling the add to cart of having an out of stick icon$).$

When it comes to the performance and usability of ReactJS, the usage of state and props strengthens the website$$s information. They both work together to provide the most accurate information for the user interface experience. As mentioned before, the state ensures that the data is updated in real time, while the props take this information and make changes by allowing the data to be sent from one component to another. This enhances the usability and performance of ReactJS by having the information stay in sync with the data and different components.
