It's tricky, but important, to decide correctly what aggregate functions should do when passed the empty set.Sometimes it's 'intuitively obvious': What is the SUM of no elements? Zero, I'm sure...

Theoretically the outcome of those functions is can't be given. The Ecma specification dictates the outcome of the Min and Max functions without arguments (See page 163). Obviously you can have all...

It's the same reason why the sum of an empty list is usually defined as 0 and their product as 1: it is the identity element of the operation. That is, whenever you include -Infinity as an element when...

The idea is, mathematically without any parameter you actually have an undefined value for the minimum. As for implementation wise, usually the min value is initialized with a very large...

I don't know for sure. But, just making a guess.Remember how we find the min. Declare a variable with an extremely high value (Infinity) and then go through the values and whenever you find a value...

Of course it would, because the start number should be Infinity for Math.min. All number that are lower than positive infinity should be the smallest from a list, if there are no smaller.And for...

When given no arguments, Math.min() equals infinity and Math.max() is -infinity.This is probably to ensure that any value is smaller than the minimum found so far, and larger than the maximum so far.

Probably because the implementation initialises an internal comparison variable to the highest (for Math.min) or lowest (for Math.max), before starting to compare against the empty arrays, and then...
