[Solved] What is the purpose of this js code?

setTimeout() only run once after certain time period (2s here (2000ms)).

setInterval() will loop forever until stoped by window.clearInterval()

your code here the timeout will have a delay for 2s then call model.increment();

your code for setInterval will repeat the sec you set at data.secondsToPlantTree
