Key Concepts

• React: JavaScript library for building UIs with components
• JSX: XML-like syntax that transpiles to React.createElement()
• Components: Functions returning JSX (must start with capital letter)
• Props: Immutable input parameters passed to components
• State: useState() Hook for managing changeable component data
• Events: onClick, onChange, onSubmit event props
• Re-rendering: State setter calls trigger component re-renders
