Learn how “this” works in JavaScript — In object-oriented programming, you typically create this blueprint with properties and methods, called the class, and based on this class, you’re able to create new objects. Now each object derived from a class will have a similar structure, but their values might be different. For instance, you and I are…

Understanding what a prototype is. — JavaScript might seem confusing for developers who’ve worked with class-based languages like C++ or Java. Even though we have a class keyword in JavaScript, it’s still not really class-based since this keyword is just syntactic sugar. It tries to mimic the class functionality from other languages but it’s ultimately still…

Anyone who’s vaguely familiar with computer programming will know what a loop is. It’s a standard way of iterating through a list of elements and there’re three most common ones which you’ll find across different programming languages, the for, the while, and the do-while loop. But when you look for…

So we’ve already created and published packages for both Node.js and Angular in this series. Now it’s time to do it for React. In the case of Angular, we had an option to natively create a “library” project and then test it inside an “application” project. We were able to…

Reusing frontend components across different projects is a neat little trick that only a few developers have. It makes your code more readable(if done correctly) and in general keeps it pleasantly organized. Your applications look more consistent and coherent when you reuse your components. Google does this very well, by…

Let’s be honest, copying code sucks. It’s a tedious, time-consuming process that solves the problem temporarily but turns out to be a burden in the long run. You could create functions and reuse them inside your project but, more often than not, you’ll find yourself wanting the same function inside…

Every organization carries out a bunch of tasks behind the scenes that most of us are not even aware of. For instance, when Netflix tells you that your account is about to expire, it’s not some guy who’s actually monitoring your account and sending you a notification about the expiration…

Rate limiting is a strategy wherein you would protect your APIs by adding a cap to their usage limit. You’d normally want your users to have a pleasant experience when using your APIs. If hypothetically, someone floods your server with requests, be it legitimate or malicious, it would cause issues…

Time and again, you sit in front of StackOverflow, trying to figure out what exactly happened in your code and why it’s not working. It’s frustrating because most of the time, the reported problem is not always immediately clear. This blog post will help you try to troubleshoot better next…
