These tricks are dozing in JavaScript since ES6 — How well do you know a language? A valid question because I always discover new things in a language, even after years of working. Today is your lucky day. These gems can make your life worthwhile inside your company’s daily grind to become the best of your team. Become a…

Oddities and secrets in JavaScript probably fewer people know — JavaScript isn’t easy to grasp. Often it does something completely different than you might expect. Undefined is a keyword… “I don’t think so, mister!”. This is just a preview of the knowledge you can gather and shine when you get asked about JavaScript. True experts know the details. Many little…

Typescript saves a lot of development time, but is it worth an entire migrating process? — I got you whenever there is a project that should be migrated to another language, your inner voice is shaking and screaming: NO GOD! PLEASE NO! …

Because .NET behaves very strangely here — Object-oriented programming languages allow you comparisons, whatever the type. Sadly, .NET does it a bit weirdly and follows strange rules. This doesn’t make comparisons straightforward and predictable. While the == operator acts as expected, calling it differently might get weird results. In .NET, there are many ways to compare. Better…

Small but mighty — The C# language was updated to 11, along with .NET 7. It brings overall improvements. The usability is dependent on your field and daily toolbelt. All in all, the changes are a mix, so there’s something for everyone. Here’s a look at its features and what the new version can…

And how to get rid of nested code — While nested code has some advantages, it is often considered difficult to read and an anti-pattern: "Flat is better than nested." Now you may wonder how to write non-nested code. Linus Torvalds, for example, is highly against nesting. Actually, you are allowed to nest, but only until level 3. Read…

And solve all kinds of problems — You might work as a programmer for years without knowing a single pattern. That’s what a lot of devs do. But not the successful ones. See, design patterns offer tested solutions. Learning patterns will help you solve all kinds of problems without reinventing the wheel every time. Hence, you and…

Explained by video game levels — Singletons are handy when you need to coordinate system-wide actions from one place—for example, database connection pools. Singletons reduce the need for global variables, which is critical in JavaScript because it limits namespace pollution and name collisions. Other patterns, like Factory, Prototype, and Facade, are often implemented as singletons. Singleton Pattern in a Nutshell

Adding abstraction always feels like the right thing — Abstraction is the good guy for every code base, right? Sure? Wrong! Undoubtedly it has 1 major hidden tradeoff many don’t even recognize. It stays undetected until it is too late, and you have to spend a lot of time decluttering coupled code that you have already abstracted so well…
