Day 31: Dates in JS - Part 2: Get Methods

Hello and welcome back to the 31st Day of the DailyJS initiative, as we discussed the last day that our topic for this week will be Dates in JS, today we will start discussing about the instance methods of the Date object.

In JavaScript, there are many instance methods available for Dates, which can be broadly classified into Get and Set methods.

When I say there are many of them, I am not exaggerating, there are many of them, but in our Dates series, we will try to discuss some important ones.

Today we will have a look at

1. getFullYear()
2. getMonth()
3. getDate()

1. getFullYear()

As the name suggests, this method gives us the "year" as a 4 digit number (YYYY)

Let's see it in action.

// Making a new date object
const currentDate = new Date();

// Let's get the current year
const year = currentDate.getFullYear();

// Print 
console.log (`Current year is: ${year}`);

2. getMonth()

This method gives us the month as a number in the range 0 to 11.

0 for January, 11 for December.

Let's see it in action

// Making a new date object
const currentDate = new Date();

// Let's get the current month
const month = currentDate.getMonth();

// Take an array of months
const months = [ 'Jan', 'Feb', 'Mar', 'Apr',
        'May', 'Jun', 'Jul', 'Aug', 'Sept', 
        'Oct', 'Nov', 'Dec' ];
// Print 
console.log (`Current month is: ${months[month]}`);

3. getDate()

This method gives us the day of the month - 1 to 31

Let's see it in action!

// Making a new date object
const currentDate = new Date();

// Let's get the current date
const date = currentDate.getDate();

// Print 
console.log (`Today is ${date}`);

Let's combine them!

// Making a new date object
const currentDate = new Date();

// Let's get the year, month and date
const year = currentDate.getFullYear ();
const month = currentDate.getMonth ();
const date = currentDate.getDate ();

// Take an array of months
const months = [ 'Jan', 'Feb', 'Mar', 'Apr',
        'May', 'Jun', 'Jul', 'Aug', 'Sept', 
        'Oct', 'Nov', 'Dec' ];

// Print 
console.log (`Today is ${date} ${months[month]}, ${year}`);

That's it for today, see you tomorrow!
