In this article, we create a function that takes in a number(num) which represents the number of seconds. So, it construct and return a string that contains information of years, days, hours and minutes contained in those seconds. Converting seconds into years, days, hours, and minutes in JavaScript involves breaking down a given total of seconds into more understandable time units. This process helps display elapsed time in a readable format. For the purpose of the article, we will consider that all the years have 365 days. Let us understand through some sample example of I/O Scenario − Sample Input ... Read More
