This code defines a function called bomb which takes two parameters count and delay. The function returns a new Promise that will resolve after the specified delay time has passed.
Inside the Promise, the setTimeout function is called with a callback function that will execute after the specified delay. The callback function will log the value of the count parameter to the console and then resolve the Promise.
In other words, if you call bomb with a count and delay value, it will return a Promise that will wait for the specified delay time and then log the count value to the console before resolving the Promise.
We then create an array named countDownDisplay to store the strings "Three", "Two", "One", and "BOOM".
We then use the for...of loop to iterate over each element in the countDownDisplay array. During each iteration, we call the executeCountDownTimer function with the current countDownDisplay and the waitTime variable. The await keyword is used before calling the function to ensure that each string of number is displayed before moving on to the next one.
