Episode notes
Array.flatMap()
- Use
Array.flatMap()to map over an array and return a flattened array. - This avoids nested arrays when returning arrays from the map function.
Array.flat()
- Use
Array.flat()to flatten arrays returned by methods likeObject.entries(). - Passing
Infinityto.flat()flattens all nested levels.
Array.fromEntries()
- Convert arrays to objects using
Array.fromEntries(). - This simplifies the process of turning arrays of key-value pairs into objects, replacing more complex
reduceoperations.
