There are statements scattered all over the internet, claiming that Redux is very hard to set up, and will leave you with a lot of unmanageable spaghetti code. I beg the differ! Using React and Redux is actually very easy, maintainable, and doesn’t really complicate things. It keeps things in system.

In this article, we’ll create a very simple application which lists names and ages. You will be able to view all listings, add listings and remove listings. We will not use any databases. Instead, we’ll simulate a database with an array of objects.

Since Redux is so incredible easy…

Firebase is an extremely good software development platform, which gives you access to both authentication, noSQL databases, storage and much more. It’s a true powerhouse, and I love the ease of using Firebase and the database Firestore.

We all know the importance of using the right tool for the job. If you’re developing an app with Firebase, you might run into a situation where cloud functions are not enough, and you need a separate backend server to do some tasks. You might even use Firebase as your main hub, and have other microservices connected to it.

Either way, if you’re…

Introduction

Have you ever wanted to write a mobile app, either for yourself or for your business? In this blog post, we’ll look into how we may write an app that runs on both iOS and Android, using the React Native framework Expo.

I’m sure you’ve heard about Expo. If not, it’s an app that makes you write a complete JavaScript app without any native code (If you work with a pure React Native app, you’ll have to do some stuff in native code as well).

The main pro and con with Expo is the native code. You won’t be able…

I was browsing JavaScript questions at Stack Overflow the other day and realized a lot of questions are about jQuery. These questions weren't about old legacy systems that needed maintenance, but new programmers who probably picked up tutorials that used jQuery.

Before

There was a time, many years ago, where there were huge differences in how browsers interpreted JavaScript. Before 2008, Internet Explorer was the most popular website browser, and they sure liked to do things a bit differently than everyone else.

jQuery was released in 2006, and one of the things it tackled, was exactly browser differences. Instead of having…

Why?

There are times when a simple Express app serving HTML is a very easy and efficient way to build a website. With all the different NPM packages out there, and a nice Bootstrap theme, you can build a nice website in Express just as fast as any Wordpress site.

Now, imagine you’ve built a website. For ease of use, you went with Express. …

The binary search will search through a sorted dataset. It’s important that the data is sorted from the lowest to the highest value, or else the binary search wouldn’t work. If your data isn’t sorted, you need to sort it before you can search over it with binary search.

The binary search is of O(log n) complexity. which basically means it will cut the data in half with each iteration, until it finds the target value we’re searching for. It will actually be much faster the more data it has to search through, compared to for example a linear search…

Such scary words. It oozes math all over them…
This is probably what you’re thinking if you’re new to computer science and programming. But really, they aren’t that hard to grasp, once you understand the basics of them.

the Big-O is a way of figuring out how efficient an algorithm is. When you’re working on a big project with a huge database, making your code run as efficient as possible can save huge costs in the long run. You may ask — What is an algorithm?

Algorithms

You can think of an algorithm as a recipe. A set of instructions on…
