It was early December of 2020 when I began to feel discomfort while sitting down during work. It was then that I noticed that there was a cyst on my left glute. At first, I didn’t make much of it because I thought that it would just go away. Guess what? It didn’t go away.

After a week of dealing with the pain, I finally decided to go to the Doctor to get it checked out. I’ll admit that it felt weird when the doctor asked me to lie down in order to take a look at the cyst. To…

Take a look at the code below. Do you see anything wrong with the NavBar component? You might even want to play around with the results if you cannot find the problem by simply looking at the code:

The Problem

If you answered history.push to the previous question, then you are correct! The problem here is that the navigation is handled using JavaScript. Let’s look at a series of steps to produce the problem:

1. Navigate to the “Result” tab in the fiddle above.
2. Right-click on either the “Home” or “About” link.

Developers often write test cases along with their code. On top of that, they even add some exploratory testing to their work pipeline. However, sometimes, there are some errors that escape their well-thought-out testing processes and end up in production.

A lot of these errors are experienced and discovered by the end users — some of them might report the problem, some might try later, or some might outright reject the product because of the error.

Thus it is important to be able to quickly react to errors that occur in production. It’s easy to debug and fix an error…

The above chart shows the price over time of a cryptocurrency that went from a little over $450 down to nothing in no time at all. This cryptocurrency is non other than BitConnect — which is probably the biggest scam ever in the history of cryptocurrencies.

The value of Bitcoin is rising again. This means that it is a good time for people to run scams because there will be a lot of new people in the crypto market. …

Those of us who have worked with functional components in React know that the introduction of Hooks has made our lives a lot easier. However, functional components have their own set of complexities and gotchas. As a result, it can sometimes be difficult to write readable and optimized functional components. Today, we will look at five simple tips to help us do just that.

1. Memoize Complex Data

Let’s take a look at the following React component called SortedListView:

This component takes an array of items, sorts them according to the comparison function provided, and displays them. However, this sorting operation could take…

Working with time zones can be rough! In fact, this article was inspired by the problems that I had with them. I finally decided to bite the bullet and do some extensive research to properly understand them. I found that they get much easier to work with when you understand the basics. This is my attempt, by putting all the basics in one place, to help anyone else who is struggling with time zones. There are also solutions to some common problems at the end.

Coordinated Universal Time (UTC): The Bread and Butter

This is the first thing we need to understand before looking at time zones. UTC…

Are you a React developer? Do you use Hooks and functional components? Do you use ESLint to ensure your code does not do anything spooky? If yes, then I am sure that you have run into the exhaustive-deps ESLint warning while using useEffect.

So, this happened about half a year ago. I was in a cafe which I frequent and I was having a pee-mergency! This place has two restrooms; one on the left and one on the right. I always went to the left side because I had never seen another male go to the right one and because ladies are always right.
