Week 9: JavaScript and jQuery

April 2, 2019

Today we will be talking about how to program for the web using JavaScript. We will be covering most of the same programming topics we discussed with Processing including: variables, arrays, loops, if statements, functions and objects. These topics are basically the same for JavaScript, just using slightly different words. We will also be talking about a JavaScript framework called jQuery that makes it much easier to write code in JavaScript.

Create a simple clock using JavaScript and jQuery. Once you have that try and do something creative with those values. Change the color of an HTML element, the size, location, etc.


  • Create a function to display the time.
  • Use the Date object to get the current time.
  • Use setInterval(displayTimeFunction, 1000); this updates the function every second.
