JavaScript getYear() Method: Date Object

Description

The getYear() method is used to get the year of a given date according to local time.

The getYear() method returns the year minus 1900; thus:

* For years above 2000, the value returned by getYear() is 100 or greater. For example, if the year is 2009, getYear() returns 109.

* For years between and including 1900 and 1999, the value returned by getYear() is between 0 and 99. For example, if the year is 1976, getYear() returns 76.

* For years less than 1900 or greater than 1999, the value returned by getYear() is less than 0. For example, if the year is 1800, getYear() returns -100.

For years before and after 2000, you should use Date.getFullYear() instead of getYear() so that the year is specified in full.

JavaScript: Tips of the Day

Reduce method

[1, 2, 3, 4].reduce((x, y) => console.log(x, y));

The first argument that the reduce method receives is the accumulator, x in this case. The second argument is the current value, y. With the reduce method, we execute a callback function on every element in the array, which could ultimately result in one single value.
In this example, we are not returning any values, we are simply logging the values of the accumulator and the current value.
The value of the accumulator is equal to the previously returned value of the callback function. If you don't pass the optional initialValue argument to the reduce method, the accumulator is equal to the first element on the first call.
On the first call, the accumulator (x) is 1, and the current value (y) is 2. We don't return from the callback function, we log the accumulator and current value: 1 and 2 get logged.
If you don't return a value from a function, it returns undefined. On the next call, the accumulator is undefined, and the current value is 3. undefined and 3 get logged.
On the fourth call, we again don't return from the callback function. The accumulator is again undefined, and the current value is 4. undefined and 4 get logged.
