create LazyMan()

Question

LazyMan is very lazy, he only eats and sleeps.

LazyMan(name: string, logFn: (log: string) => void) would output a message, the passed logFn is used.

LazyMan('Jack', console.log)
// Hi, I'm Jack.

He can eat(food: string)

LazyMan('Jack', console.log).eat('banana').eat('apple')
// Hi, I'm Jack.
// Eat banana.
// Eat Apple.

He also sleep(time: number), time is based on seconds.

LazyMan('Jack', console.log).eat('banana').sleep(10).eat('apple').sleep(1)
// Hi, I'm Jack.
// Eat banana.
// (after 10 seconds)
// Wake up after 10 seconds.
// Eat Apple.
// (after 1 second)
// Wake up after 1 second.

He can sleepFirst(time: number), which has the highest priority among all tasks, no matter what the order is.

LazyMan('Jack', console.log).eat('banana').sleepFirst(10).eat('apple').sleep(1)
// (after 10 seconds)
// Wake up after 10 seconds.
// Hi, I'm Jack.
// Eat banana
// Eat apple
// (after 1 second)
// Wake up after 1 second.

Please create such LazyMan()

Code

// interface Laziness {
//   sleep: (time: number) => Laziness
//   sleepFirst: (time: number) => Laziness
//   eat: (food: string) => Laziness
// }

/**
 * @param {string} name
 * @param {(log: string) => void} logFn
 * @returns {Laziness}
 */
function LazyMan(name, logFn) {
  // your code here
}
