How to Generate An Array of Years Between Two Dates In Javascript

March 14, 2020

javascript

1.function generateYearsBetween(startYear = 2000, endYear) {
2.    const endDate = endYear || new Date().getFullYear();
3.    let years = [];
4.  
5.    for (var i = startYear; i <= endDate; i++) {
6.      years.push(startYear);
7.      startYear++;
8.    }
9.    return years;
10.}

This generates an array of years between the startYear and endYear. startYear defaults to 2000 and endYear defaults to the current year using the Date() function.

Usage

1.const yearsArray = generateYearsBetween(2007, 2014);

This will generate the following array of years:

1.[2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014];

While Loop

You can accomplish the same thing using a while loop:

1.function generateYearsBetween(startYear = 2000, endYear) {
2.    const endDate = endYear || new Date().getFullYear();
3.    let years = [];
4.  
5.    while (startYear <= endDate) {
6.      years.push(startYear);
7.      startYear++;
8.    }
9.    return years;
10.}
