why does const current = setInterval(() => setSeconds(seconds => seconds + 1), 1000) work but not const current = setInterval(() => setSeconds(seconds + 1), 1000) ? what is the difference between those two?
const current = setInterval(() => setSeconds(seconds => seconds + 1), 1000)
const current = setInterval(() => setSeconds(seconds + 1), 1000)
Hi Siyu! Thanks for the question. An arrow function makes an implicit return :) so we can see the incrementing of time visually on the browser page.
What do you mean exactly by "An arrow function makes an implicit return"?
