Study Notes
React Component Development and State Management
- Essential prop needed for fetching props from an API is a key
- Mouse events include enter, move, down, up, leave, over, out
- Mouse down on a button makes it appear pressed
- Mouseenter points move inside an element, while mouseleave points move outside an element
- Parameters event listeners receive are functions, defined before the return
- Using states in React is crucial for the UI to reflect the state of a list
- Before React, changing the DOM involved appending the state of a list into the DOM tree
- React allows automatically hooking onto a state for new states to be added
- useState and set give the component attributes, treating it like an object that changes based on those states
- setState is a method that takes an object as a parameter to describe the changes to the state
- Props refer to properties passed into a React component, with the restriction of being immutable
- State refers to values managed by the component itself, similar to variables declared inside a function
