Given the available data of month, year, and duration, the task is to iterate through the months for the specified duration and determine the month at the end of that period.
For instance, If the chosen month is March 2015 and the duration is 4 months, the desired outcome would be November 2014 - which is 4 months prior to the selected month.
How can this be best achieved?
momentjs is a great tool for handling date and time in JavaScript:
let currentDate = new Date;
let threeWeeksAgo = moment(currentDate).subtract(3, 'weeks');
If your dates are in the format "Apr 2021", you can easily create a date object using
let yourDateObject = moment('Apr 2021')Here is how you can achieve a similar result:
function updateDate(initialDate, months){
var date = new Date(initialDate);
date.setMonth(date.getMonth() + months);
return date;
}
The parameter months indicates the number of months to add or subtract from the initial date. This code uses plain JavaScript and does not require any additional libraries.
For example:
updateDate('Mar 2015', -4);
