For Loops! A New Kind of Loop, Computer Programming

Repetitive tasks, like the scenes from the movie Ground Hog Day, are common in computer programs. But how exactly do you program a piece of code to repeat specific instructions? This is where the While loop comes in handy. This video...

A loop within a loop is called a nested loop. It expands the repeating code based on two different variables. The video shows an example of drawing an image across and down a screen.

Starting with an empty computer screen for a coder can be as intimidating as a bare canvas to a painter or a blank sheet of paper to a writer. Where do you start? If you know what you are trying to build, then you just pick something and...

Explore, create, and make mistakes. This is the call to action in a video on how to use Khan Academy to learn to write Java code. The speaker encourages learners to feel comfortable with the programming environment that is provided on...

In computer programming, loops and arrays are made for each other. This video describes adding a while loop to print out each element in an array and then doing the same procedure using a for loop.

Similar to using variables, object properties can be changed in the program. However, you can also dynamically add new properties while the program runs. The video shows how to define an object, use an object property, change an object...

Creating interactive programs can be very exciting for new computer programmers. The author shows how to use mouseIsPressed within a conditional statement to create a small JavaScript program that responds to the user's mouse press.

An instructional video combines arrays, loops, and mouse clicks. The author shows how to modify JavaScript code to add a balloon each time the mouse is clicked. The video also shows two different ways to add to the end of the array: one...

Start being creative with your JavaScript text. The speaker defines a string and how to combine strings. The program modeled here displays the text, and using the mouseX and mouseY functions, the text grows as it moves. Your beginning...
