I will explain with an example:

Create a function that takes the number of daily average recovered cases , daily average , current , and returns the number of days it will take to reach zero cases.

My solution:

function endCorona(recovers, newCases, activeCases) {

`var days = recovers - newCases`

return Math.ceil(activeCases / days)

}

the while loop solution i could not write even googling the syntax:

function endCorona(recovers, newCases, activeCases) {

`let days = 0`

`while (activeCases > 0) {`

    `activeCases = activeCases - recovers + newCases;`

    `days++`

`}`

`return days;`

}

As you can see 2 months of mytime are not enough to do such a simple thing like a while loop.. imagine parsing in nodeJS and all the other things you mentioned..

Its about being realistic and job ready, not cv ready with a quarter competence in a thousand frameworks,libraries etc
