Intro to Code Part VII – Arrays and Loops

A loop

Repeat as necessary

Part Seven of our Intro to Code series dealt with loops and arrays and ended up being a pretty quick class. Arrays and loops aren’t terribly hard to understand and, for those who have been doing our suggested homework, last night wasn’t the first time you’d seen them, but being able to work comfortably with both concepts is critical for web development.

In class, we went over a brief slide presentation on how JavaScript arrays work and some of the built-in methods for working with them. We also got some practice in with for loops, which are the most common type of loop when working with arrays.

Next class, we’ll be working with JavaScript Objects and also combinations of arrays and objects. Historically, that has been a sticking point for CodeSLO members but we’ve got some new ideas to try this time around and hopefully we’ll keep everyone progressing.

As a side note, I was very pleased with the skill level I saw in last night’s class. Everyone seems to be doing really well with their coding studies and many people are now well ahead of the required material.

We only have another four classes in this series and we’re really going to bring the material in hard and fast over the next few sessions. The secret to keeping up is just to do the homework and code a little bit every day.

Here is a link to the slides from last night’s class.

Our homework is to complete the beginning algorithm challenges at Free Code Camp. There are only six left, so go knock them out!

You might also think about making a basic website or two. We’ll be bringing our JavaScript back to the web page in part nine and keeping it there for the remainder of the series. Make sure your HTML and CSS skills are fresh!

Also, don’t forget to leave reviews for us on Facebook and We like to show that we are of value to the community, so, if you think what we do is awesome, please let the world know.

Code on!
