Math, Date, and String

When building complex applications using JavaScript, there will be times when you need to deal with string manipulation, math calculations, and dates. Luckily, JavaScript has several built-in methods for this type of data. In the following exercises, we will go over the ways we can utilize these in our applications.

To create a new Date object, use the following command:

const currentDate = new Date();
