AlgoDaily - Understanding Big O Notation and Algorithmic Complexity

Let’s now see how much time the previous function takes to execute. In a Jupyter Notebook or any language interpreter, you can use the following script to find the time taken by the algorithm.

xxxxxxxxxx
 
function customPower(x, y) {
    let result = 1;
    for (let i = 0; i < y; i++) {
        result = result * x;
    }
    return result;
}
​
​
var start = new Date().getTime();
console.log(customPower(3, 4));
var end = new Date().getTime();
​
console.log(`Call to customPower took ${end - start} milliseconds`);
