JavaScript Code:
function check8(x, y) {
if (x == 8 || y == 8) {
return true;
}
if (x + y == 8 || Math.abs(x - y) == 8)
{
return true;
}
return false;
}
console.log(check8(7, 8));
console.log(check8(16, 8));
console.log(check8(24, 32));
console.log(check8(17, 18));
Sample Output:
true true true false
Flowchart:

ES6 Version:
function check8(x, y) {
if (x == 8 || y == 8) {
return true;
}
if (x + y == 8 || Math.abs(x - y) == 8)
{
return true;
}
return false;
}
console.log(check8(7, 8));

Previous: Write a JavaScript program to compute the sum of the two given integers, If the sum is in the range 50..80 return 65 other wise return 80.
Next: Write a JavaScript program to check three given numbers, if the three numbers are same return 30 otherwise return 20 and if two numbers are same return 40.

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
