Calculate If Duplicates Exist In An Array Using JavaScript

February 2, 2015

You’ll notice previously I did a post regarding the Fibonacci number, a popular interview question for programming jobs. To keep up with this trend of interview questions, we’re going to look into the different ways of finding duplicates in an array.

Finding array duplicates is a good question because it tests your knowledge of algorithm design and your understanding of various time complexities.

Not too long ago I wrote a very popular tutorial for integrating Crosswalk into your Ionic Framework mobile application. Since then, the guys at Ionic released version 1.3.2 of their CLI and it makes the process even easier than I had previously demonstrated.

The CLI integration is still beta and there is a lot of confusion around it, but this article should clear things up in regards to its usage.

If you’re familiar with the material I write on my blog, you’ll probably be confused at why I’m making such a post. Anyone who has been a part of a Computer Science program at a university will probably have dabbled with Fibonacci in their first semester of school. However, many Computer Science graduates don’t realize that this is a common job interview question regardless of the company or job level that you’re applying for. Whether you’re applying for a new graduate position or a senior level position, there is a good chance you’re going to be screened with a question on this topic.

With that said, I think this can be a refresher to anyone going through the interview process for a programming or software engineering position.

Since starting this blog in July of 2014, I have had an unexpected amount of growth. So much, that a lot of strain has been placed on my virtual private server (VPS).

A common issue that has plagued me and many other WordPress users is the awful MySQL crash due to exhausted resources. This is because the server has run out of resources due to traffic spikes or other anomalies. The worst part for me is that MySQL tends to crash while I’m sleeping, putting my blog out of commission for up to six hours at a time. This is not good when you’re trying to be a reliable source of information on the internet.

Luckily, I’ve developed a script that will elegantly resolve these related problems.

I’ve received a few requests from my subscribers for an article regarding embedding videos in their Ionic Framework application. This could be a challenging task for a few reasons. There are known issues with the HTML5 <video> tag for Android. One might also ask how to make the videos responsive for multiple screen resolutions.

In this guide, I’m going to show how to do responsive embeds of YouTube videos into an Ionic Framework list of cards.

I’ve still been doing a lot of fiddling with Express web framework for Node.js. I recently ran into an issue with saving data to sessions because much of the documentation online is outdated and no longer functional. However, I did get it working, and am going to discuss it in this guide.

If you’re not familiar with Express, you may want to take a moment and read my other article regarding installation.

So you’ve been playing around with Ionic Framework for a while now and have decided that maybe $ionicPopup dialogs are not meeting your needs because they don’t look native enough. As we’ve come to expect, Apache Cordova has a plugin for us to correct this, giving us native device popup dialogs in our hybrid application.

This guide will show you how to use the Apache Cordova Dialogs plugin in your Ionic Framework Android and iOS mobile application.
