CodeFights - JavaScript code to determine which deadlines in an array are classified as being due 'today', 'upcoming', or 'later', based on the day they are expected to be completed.

taskTypes.js

function tasksTypes(deadlines, day) {
	var resultArray = new Array(3);
	var today = 0;
	var upcoming = 0;
	var later = 0;

	for(i=0; i<deadlines.length; i++){
		if(deadlines[i] <= day) {
			today++;
		}
		if(deadlines[i] > day && deadlines[i] <= day + 7) {
			upcoming++;
		}
		if(deadlines[i] > day + 7) {
			later++;
	}
	}

	resultArray[0] = today;
	resultArray[1] = upcoming;
	resultArray[2] = later;
	return resultArray;
}
