List of Overlapping Scenarios

Date Object

A timespan is an interval of time represented by 2 dates in time. Usually start and end. The difference between the 2 dates is the total duration of the timespan.

Write a function, isOverlapped that takes in 2 timespans and determines if they overlap.

function isOverlapped (timespanA, timespanB) {
	//return true if overlapping, false otherwise
}

For this exercise, represent timespans as objects:

var christmasTimespan = {
	start: new Date("December 25, 2015"),
	end: new Date("December 26, 2015")
};

Sample Data and Outcomes

Use moment.js instead of JavaScript Dates and repeat the isOverlapped exercise.

A timespan should be an object with Moments:

var christmasTimespan = {
	start: moment("2015-12-25"),
	end: moment("2015-12-26")
};

Useful documentation:

• Moment Parsing
• Moment Queries

Given 2 arrays of timespan objects, return any conflicting timespans between the 2 arrays.

function scheduleOverlap(scheduleA, scheduleB) {
	// return an array of any overlapping timespans.
}
