If statement with date comparison

Question

I'm trying to write an if statement that runs some code if the date is after April 24th, 2017, 10 am EDT, but it doesn't appear that my variables are comparable (different data types?).

I'm trying to avoid using Moment.js for just this.

var today = new Date();
var launch = 'Mon Apr 24 2017 10:00:00 GMT-0400 (EDT)';

today returns Tue Apr 04 2017 14:34:41 GMT-0400 (EDT).

When I test if either is greater than the other, both are false. How should I format my dates?

Thanks!

You have to have launch as a date type:

var today = new Date();
var launch = 'Mon Apr 24 2017 10:00:00 GMT-0400 (EDT)';
var launchDate = Date.parse(launch);

if ( launchDate > today )

You should also read more about dates here: Compare two dates with JavaScript

Gotcha. I knew I was missing something like this. Thanks! – Mario Parra Apr 04 '17 at 18:44
I understand what this does, but for some reason, when I `console.log()` both variables, they both return today's date. – Mario Parra Apr 04 '17 at 18:54
corrected the syntax. You have to do a parse because it's a string. – Avitus Apr 04 '17 at 19:00
@MarioParra that is because the console.log is coercing the `today` variable into a string display. – danatcofo Apr 04 '17 at 19:01
@Avitus Thanks, but then `launchDate` was formatted in Unix, whereas `today` wasn't, so I used `today = Date.now();` instead. – Mario Parra Apr 04 '17 at 19:03
