Which is the best to use either the State variables or Properties in ReactJS and why

Question

Accepted Answer

State variables are best for managing component's internal state, while properties are best for passing data from parent to child components.

State variables are mutable and can be changed within the component
Properties are immutable and cannot be changed within the component
State variables are used to manage the component's internal state
Properties are used to pass data from parent to child components
State variables are defined within the component's constructor
Properties are defined in the parent component and passed down to the child component as props
Using state variables can cause unnecessary re-renders, so use them sparingly
Using properties can improve performance as they are read-only and cannot be changed within the component
