One thing we can do to solve problems coding is to use the Date object to compare the dates and times to conditionally to a certain logic in our code. This article takes a look at how to use the date object to compare two dates to see what is the next (or previous) date.
JavaScript has a built-in data object that it can use access methods that can help us do timestamp- based logic . To configure it, instantiate a new date by encoding the following:
If you were to enter console.log (date)
, the time (the substring after T ) it will be different depending on where you live by default. If you want to work with UTC, remove the Z and add + HH: MM
or -HH: MM
.
Know how to define what is important when working with our compare function in the next section.
Next, take a look at the methods offered when using the date constructor. One such method is getTime ()
. We use this method to change our date object to a number so that it can be easily compared.
This particular method converts the date to the number of milliseconds since the start of the epoch (the epoch started on January 1, 1970). Here is our getTime method:
Since the date is instantiated as a new Date object, we can use the dotted notation to access the getTime function.
I recommend checking the documentation for all the different types of methods you can use on the Date object in your logic. We are now ready to face our prompt
