[JavaScript] Quick tip on finding the last element in an array that matches your criteria. lastFind() method works the best here. It became available not that long ago, but already well supported by browsers. So you can use it safely now.

[JavaScript] Quick tip on improving error handling. Use the property cause to refer to the initial error or just to pass any context when throwing an error. This prop is optional, and it’s missing if you don’t pass anything. Also, it’s important to mention that it’s currently not supported by the Opera browser. All other browsers support it.

[JavaScript] Decorators are still a new feature in #javascript and isn’t fully here yet (still a proposal), but we can start using them already (for example, in #typescript). Decorators are actually quite helpful in some cases, let’s list some of them here.

[React.js] Let’s dive into one of the latest hooks in #reactjs - useDeferredValue. It might be not obvious in the beginning why it’s needed at all. But after reading through this post you’ll definitely get few ideas about it.

[Web Dev] Usually we learn how to write code, but nobody teaches us how to debug and improve our solutions. But it’s critical to understand debugging and its best practices in order to build efficient applications. This post provides some thoughts on Profiling, which is debugging technique for measuring performance. The first step whenever you want to improve/fix issues in your app. What would you add from your experience?

[TypeScript] Do you know the role of the “declare” keyword in #typescript? It helps to reduce the gap between JS runtime environment and the TS type checking system. Basically, you need it to explicitly type an untyped (often third-party) code. Look at the examples to see some use cases.

[Web Dev] Redirects vs. Rewrites

This sounds like a simple question, but would you be able to answer it from top of your head? Here’s the quick summary on how redirects are different to rewrites when we talk about web development. Thank me later after nailing this question on a technical interview 😎

Promise.withResolvers() method is a new way of dealing with promises in #javascript . It feels much better using this method when you need to manage resolve and reject functions outside of the executor function. #webdev #webdevelopment #typescript #webdeveloper #nodejs #frontend #programmer

After the recent release of Deno V2 I started seriously considering to migrate away from Node.js. Node still has a huge advantage in terms of ecosystem, but look at this 5 points: Deno is a game-changer from different perspectives. Built-in support of TypeScript is already a big deal. Are you thinking about migration too?

Consequent question: Deno or Bun? They both are great tools, from my point of view. Here I have listed how they approach different aspects of the web development. So it depends on you what to choose, but make sure you read it first.
