Importance of Algorithm Complexity

To study the importance of algorithm complexity, let’s write two simple programs. Both the programs raise a number x to the power y.

Here's the first program: see the sample code for Program 1.

xxxxxxxxxx

function customPower(x, y) {

    let result = 1;

    for (let i = 0; i < y; i++) {

        result = result * x;

    }

    return result;

}

​

​

console.log(customPower(3, 4));
