6.8.2: Using Date methods.

Assign daysPassed with the number of days passed since the world wide web was born and today. Hint: 1000 milliseconds are in a second, 60 seconds are in a minute, etc.

var interestingEvents = { "Long distance telegraph": new Date(1844, 4, 24), "First telephone call": new Date(1876, 2, 10), "Microsoft founded": new Date(1975, 3, 4), "World wide web born": new Date(1989, 2, 1), "Google founded": new Date(1998, 8, 4), "Facebook website launch": new Date(2004, 1, 4) }; var interestingDate = interestingEvents["World wide web born"]; // Code also tested using date of First telephone call var daysPassed = 0;
