everyIsPositive
Given an array of numbers, use the `every` method to check if all numbers in the array are positive.
Examples
everyIsPositive([1, 2, 3]) → true
everyIsPositive([1, -2, 3]) → false
Starter code
function everyIsPositive(arr) {
}
Complexity of the optimal solution
Time O(n), space O(1). The `every` method iterates through the array, but stops as soon as it finds an element that does not satisfy the condition. In the worst case (all elements are positive), it checks all 'n' elements. Space is constant.
