Episode notes
React vs. HTML Event Handling
- React uses camel case for event handlers (onClick) while HTML uses lowercase (onclick).
- React event handlers receive a synthetic event object, not the native browser event.
JavaScript Data Types
- JavaScript has seven primitive data types: number, string, boolean, null, undefined, symbol, and object.
- Wes Bos successfully listed all seven after initially struggling.
Promise States
- Promises have three states: pending, fulfilled (resolved), and rejected.
- Scott Tolinsky correctly identified the states despite some initial uncertainty.
