Challenge: Print Numbers Sequentially
This challenge will test your skills in implementing async/await with promises in JavaScript.
We'll cover the following
Problem statement #
In this challenge, you need to print the numbers 0-9 in a sequential manner, so that each number is printed after a random waiting time. For example, i=0
might wait 4 seconds before being printed, whereas i=1
might wait 2
seconds before being printed. You need to use the sleep
function (given below) to achieve this. However, it will cause values to be printed in a non-sequential manner. Your task is to write the code in a way that the values are printed in a sequential manner.
You need to implement the concept of
async
/await
in this exercise.
