Recently, I was introducing a colleague to TypeScript, and the first thing we did was create a simple “Hello World” program. It’s always best to start with the basics when learning a new programming language. In this article, I will explain different ways to create and run a “Hello World” program in TypeScript, from setting … Read more >>
While building a configuration management utility for a client project, I had to merge objects in TypeScript. In that case, I just needed to combine two objects, but it became more complex when I had to deal with deeply nested properties, overlapping keys, and type safety. While searching for a solution, I found several ways … Read more >>
Recently, I was working on a TypeScript project that required displaying simple notification messages to users. The most straightforward approach was to use alert boxes. Alerts are one of the simplest ways to show messages to users in web applications. They’re easy to implement and universally supported across browsers. In this article, I’ll show you … Read more >>
Recently, I was working on a large TypeScript project where we needed better error handling than just using the default Error class. We have to handle different types of errors, like validation issues, API failures, or business logic problems, in an organized way. The issue with the standard error class is that it doesn’t give … Read more >>
In one of my recent TypeScript projects, I designed a system that required different devices to support a set of common functionalities. In that, some devices could connect to Wi-Fi, others could stream content, and a few could do both. After searching for solutions, I found out that it can be done using the extends … Read more >>
While working on a TypeScript project, I needed to loop through an object and access its keys and values dynamically. At first, I used a regular for…in loop, but TypeScript code threw an “TS7053” error while looping through an object. In this tutorial, I’ll explain the different ways to loop through objects in TypeScript and … Read more >>
In TypeScript, both satisfies and as operators are used to work with types, but they behave differently. The satisfies operator checks that an object matches a specific type without losing extra properties. On the other hand, the as keyword forces a type on a value, even if it doesn’t fully match, which can lead to … Read more >>
As a TypeScript developer with over six years of experience, I’ve worked on numerous projects where even the simplest operations, such as adding two numbers, must be implemented correctly. While adding numbers might seem trivial, understanding the TypeScript approach to doing so opens doors to improved type safety and code quality. In this article, I’ll … Read more >>
Over the past six years, I’ve worked with TypeScript and witnessed its evolution, incorporating many powerful features. One operator that significantly improved type checking in my projects is the satisfies operator introduced in TypeScript 4.9. This operator has been a game-changer for ensuring type correctness while preserving type information. In this article, we will learn … Read more >>
While building a TypeScript project, I got a requirement where I had to handle different types of user profiles depending on the user’s state. Each profile had common fields but also unique details like beach preferences for California or BBQ choices for Texas. To handle this in a better way, I used TypeScript generic object … Read more >>
