Answer 1

Use the for in loop with objects to iterate over the keys. To iterate over the values of an iterable you must use the for of loop.
At line 3 make in as of.

Answer 2

for(x in array) returns the index of each elem in the array .
try
for(x of array)

Answer 3

you could use reduce() array method:

function smallestNum(array) {
return array.reduce(
(a,v) => v<a ? v : a,
Infinity
);
}

Thanks I didn't understand the difference between in/of and thought they were interchangable
