26. The essence of Molecule • Taking the Compose engine, turning it on, and having it emit new values into a state flow for consumption. • Compose handles recording values, and if it decides your function needs to be recomposed, it handles recomposing and emitting the new value. • “The use cases are really only limited by your imagination” - Jake Wharton https://www.youtube.com/watch?v=O70beCWbSCY
