Discussion on: Explain React.js Like I'm Five

I’m drawing a finger painting and really want a yellow background but I only have three colour to use: red, green or blue.

With JavaScript, I add red paint to the canvas first, which makes the colour change. It looks different now; the state has changed. Next, I add some green paint and the colour changes to yellow (along with the canvas state).

With React.js I can mix the colours beforehand using a pot, which React calls a component, just before the canvas (and state) is updated.

Both ways work just fine but it’s bit annoying having to add the colours individually and keep track of the changing colours on the canvas. It’s much easier to mix the colours beforehand and add them straight to the canvas.

Now that is a "like I'm five" explanation! That's great, thank you. :)
