Javascript Deep Dive

This document is written to help JavaScript developers to understand JavaScript's weird parts deeply and to prepare for interviews, the following resources was really helpful to write this document:

	test_employees_1 = [[1,5,[2,3]],[2,3,[]],[3,3,[]]]; // id = 1 11
	test_employees_2 = [[1,7,[2,3]],[2,1,[]],[3,2,[4]],[4,3,[]]]; // id = 1
	test_employees_3 = [[1,2,[5]],[5,-3,[]]]; // id = 5 -3
	test_employees_4 = [[1,10,[2,3,4]],[2,-1,[]],[3,-2,[]],[4,-3,[]]]; // id = 3 -2


	function mapEmployeesToObj(arrEmployees) {
	const employeeObj = arrEmployees.reduce((acc, item) => {
	const id = item[0];
	const value = item?.[1] ?? 0;

	const scheduled = [[10, 5], [25, 15]];
	const newPrograms = [[18, 7], [12, 10]];

	const checkOverlap = () => {
	const result = newPrograms.map((program, index) => {
	let overlaped = false
	const scheduledLength = scheduled.length
	const [startTimeNew, execTimeNew] = program
	const endTimeNewProgram = startTimeNew + execTimeNew
	let count = 0
