function wait() {
let a = Date.now()
while (Date.now() - a < 3000) {
//loop
}
console.log('waiting ends...')
}
function start(){
console.log('starts...')
wait()
}
function end(){
console.log('ends...')
}
start()
end()
How can I set wait() execute asynchronously that lead to a output of “starts…, ends…, waiting ends…” without apply setTimeout function to wait()?
