Fix the getFullYear() is not a function error in JavaScript

In this tutorial, we are going to learn about how to Fix the getFullYear() is not a function error in JavaScript

When we try to use JavaScript Date().getFullYear() method without using new keyword we get the following error in our console.

const year = Date().getFullYear();

console.log(year);

VM381:1 Uncaught TypeError: Date(...).getFullYear is not a function
    at <anonymous>:1:21

To fix the getFullYear() is not a function error, Make sure to call the getFullYear() method on a new Date() constructor.

The getFullYear() method returns the current year in Four digit format eg: 2022.

Here is an example:

const year = new Date().getFullYear();

console.log(year);

Output:

2022

Sometimes, we need a customized date and time instead of the current time. to do that we can also pass the the vaild date and time to new Date() constructor.

Here is an example:

const year = new Date('Aug 19, 22 11:20:18').getFullYear();

console.log(year); // 2022
