While working on a TypeScript project, I needed to add extra information (metadata) to classes and their properties, such as logging when a method runs or validating input, without modifying their actual implementation. That’s when I discovered TypeScript decorators. Decorators allow you to add metadata, modify, or extend the behavior of classes, methods, and properties … Read more >>
As a TypeScript developer with years of experience, I’ve found that promises are one of the most powerful features when dealing with asynchronous operations. Whether you’re fetching data from an API, reading files, or executing time-consuming tasks, promises help you manage the flow of your application. Recently, I was working on a TypeScript project where … Read more >>
I was working on a TypeScript project, and I often encountered values that could be null or undefined. I had to repeatedly check for null, which made my code lengthy and difficult to read. Then I discovered TypeScript’s non-null assertion operator (denoted by an exclamation mark). This small symbol helped me write cleaner code while … Read more >>
Recently, I was building a TypeScript-based healthcare application where I needed to create different views of the same user data like some for public display, some for internal medical staff, and others for account settings. The issue was that each view required removing a different set of sensitive or internal-use-only properties from a complex interface. … Read more >>
Recently, while working on a TypeScript feature that involved updating specific fields on an object, I ran into a problem. I wanted to allow dynamic property access, but only for specific fields, and TypeScript wasn’t providing the safety as required. After searching for solutions, I found out that we can use the keyof operator along … Read more >>
Recently, I was working on a TypeScript project where I had to fetch user data from an object based on dynamic string IDs. In that process, I got a TypeScript compile error stating that we couldn’t index the object with a string. After searching for the solutions, I came to know that the issue was … Read more >>
Recently, I was working on a TypeScript project for a financial services company where we needed to simplify our codebase. One feature I found incredibly useful was the ternary operator, which helped us reduce complex if-else statements into clean, single-line expressions. In this article, I’ll show you how to effectively use the ternary operator in … Read more >>
When I first started working with TypeScript classes, I was searching for solutions to multiple ways of constructing an object in TypeScript, similar to those in Java. After searching, I discovered that TypeScript doesn’t support traditional constructor overloading. However, with an alternative approach that utilizes multiple constructor signatures and a single implementation, we can achieve … Read more >>
Recently, I was working on a TypeScript project where I needed to process user transactions in the exact order they were received. The issue was that there’s no built-in Queue data structure in TypeScript. So we need a proper implementation to handle this common scenario. In this article, I’ll explain various ways to implement queues … Read more >>
Recently, I was working on a project where I needed to implement complex conditional logic in TypeScript. After years of using JavaScript, I’ve found that TypeScript’s type system makes if-else statements much more powerful and reliable. In this blog, I’ll explain different ways to use TypeScript’s if-else conditional logic, along with practical examples that go … Read more >>
