Question

I have two date strings like this:

var startDate = \'2012-04-01\';
var endDate = \'2014-11-01\';

And I want to end up with an array of stri

All solutions above run in O(n^2) time complexity, which is not very efficient. See below solution in O(n) time complexity:

function getAllMonths(start, end){	
	let startDate = new Date(start);
	let startYear = startDate.getFullYear();
	let startMonth = startDate.getMonth()+1;
	
	let endDate = new Date(end);
	let endYear = endDate.getFullYear();
	let endMonth = endDate.getMonth()+1;
	
	let countMonth = 0;
	let countYear = 0;
	let finalResult = [];

	for(let a=startYear; a<=endYear; a++){

		if(startYear0){
				countMonth += 12;
            }
			countYear+=1;
			startYear++;
        }else 
		if(startYear==endYear){
			countMonth+=endMonth;
        }
    }
	for(let i=startMonth; i<=countMonth+startMonth; i++){
		finalResult.push(startDate.getFullYear()+(Math.floor(i/12)) + "-" + Math.round(i%13) + "-" + "01");
    }
	return finalResult;
}

getAllMonths('2016-04-01', '2018-01-01');

Might share a much more simpler code
