Hi Megha Pathak congratulations to you on your new job role at Hashnode. I love your write up, I love Hashnode and look forward to an awesome experience working at Hashnode someday!
The first code in your article could be refactored to the following;
const num2 = 3;
const multiplyBy2 = function (inputNumber) {
return inputNumber*2;
};
// multiplyBy2(10) Output = 20, and multiplyBy2(num2) Output = 6
// It can even be slimmed down more further.
const num2 = 3;
const multiplyBy2 = inputNumber => inputNumber*2;
// multiplyBy2(10) Output = 20, and multiplyBy2(num2) Output = 6
This is for anyone willing to learn other ways to simplify the code even further and also see how Higher Order Functions come into play!
Happy Coding!
