Looping Through Arrays, Computer Programming

Learning how to write computer code has never been so much fun! Given control of their very own robots, children create simple programs in order to solve a series of challenges and develop their problem solving skills.

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...

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...

Now that you are familiar with while loops let's look at a new type of loop: the for loop. This video shows the three parts of the for loop: the start, the Boolean test, the value change, and how it differs from a while loop.

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...

Expand your beginning coder's use of objects in programs by looking at examples where you can change code to define and use objects in arrays and pass objects as parameters to a function. All of this leads to a deeper understanding of...

The next step in your class's development as young programmers is learning to define and use a simple function in JavaScript code. Younger students may require some additional explanations to help highlight the importance of functions....

As the author in this video states, "Life is complex." To handle this complexity, programming languages use something called Boolean operators. In a simple JavaScript code example, this video shows how to set up a conditional statement...
