JavaScript Code:
function positive_negative(x, y)
{
if ((x < 0 && y > 0) || x > 0 && y < 0)
{
return true;
}
else
{
return false;
}
}
console.log(positive_negative(2, 2));
console.log(positive_negative(-2, 2));
console.log(positive_negative(2, -2));
console.log(positive_negative(-2, -2));
Sample Output:
false true true false

JavaScript: Tips of the Day
Returns the sum of the powers of all the numbers from start to end (both inclusive)
Example:
const sumPower = (end, power = 2, start = 1) => Array(end + 1 - start) .fill(0) .map((x, i) => (i + start) ** power) .reduce((a, b) => a + b, 0); console.log(sumPower(10)); // 385 console.log(sumPower(10, 3)); // 3025 console.log(sumPower(10, 3, 5)); // 2925
Output:
385 3025 2925
