Hello friends, In this post you will find a javascript code that helps you to get last 3 months name with current year using javascript function. This is really helpful for those also who are working in lightning component or lightning web component.

Get last 3 months name in javascript

Here, I am writing two types of function, first one print fullyear and second print last 2 digits of year. 

1.) With full year:

 function getLast3MonthsWithFullYear() {
    var monthNames = ["", "January", "February", "March", "April", "May", "June","July", "August", "September", "October", "November", "December"];
    var months = new Array();
    var today = new Date();
    var year = today.getFullYear();
    var month = today.getMonth();
    var i = 0;
    do {
        months.push(monthNames[parseInt((month > 9 ? "" : "0") + month)] + "-" + year);
        if (month == 1) {
            month = 12;
            year--;
        } else {
            month--;
        }
        i++;
    } while (i < 3);
    return months;
 }
 document.write(getLast3MonthsWithFullYear());

Output:

 2.) With last 2 digits of year:

 function getLast3MonthsWith2DigitYear() {
    var monthNames = ["", "January", "February", "March", "April", "May", "June","July", "August", "September", "October", "November", "December"];
    var months = new Array();
    var today = new Date();
    var year = today.getFullYear().toString().slice(-2);
    var month = today.getMonth();
    var i = 0;
    do {
        months.push(monthNames[parseInt((month > 9 ? "" : "0") + month)] + "-" + year);
        if (month == 1) {
            month = 12;
            year--;
        } else {
            month--;
        }
        i++;
    } while (i < 3);
    return months;
 }
 document.write(getLast3MonthsWith2DigitYear());

Output:
