The value [1, 2, 3, 4, 5] will be displayed in the console. At first, this seems counterintuitive since the value of n decreases, but the values in the final array are increasing.

This happens because the push happens last, after the recursive call has returned. At the point where n is pushed into the array, countup(n - 1) has already been evaluated and returned [1, 2, ..., n - 1].

It is considered best practice to format multiple conditional operators such that each condition is on a separate line, as shown above. Using multiple conditional operators without proper indentation may make your code hard to read. For example:

function findGreaterOrEqual(a, b) { return (a === b) ? "a and b are equal" : (a > b) ? "a is greater" : "b is greater"; }

The following function uses an if/else statement to check a condition: function findGreater(a, b) { if(a > b) { return "a is greater"; } else { return "b is greater or equal"; } }

This can be re-written using the conditional operator: function findGreater(a, b) { return a > b ? "a is greater" : "b is greater or equal"; }
