Intersection Types In TypeScript
Updated on · 4 min read|Intersection types provide a way of combining multiple types into one, enabling the creation of sophisticated type systems that can enhance the development workflow and maintainability of the code. This post explores the basics of intersection types in TypeScript and how they can be used to create more robust type systems.
Working with Union Types In TypeScript
Updated on · 6 min read|Union types in TypeScript offer a versatile way to define variables and functions that are intended to handle more than a single data type. This post will demonstrate how union types wor in TypeScript and will touch upon their declaration, usage in functions, and practical examples.
Understanding and Implementing Type Guards In TypeScript
Updated on · 9 min read|Type guards are a powerful feature in TypeScript that allows you to narrow down the type of an object within a certain scope. With type guards, you can perform specific checks to determine the type of an object and then use that object in a way that is type-safe according to the TypeScript compiler. In this post, we'll look into the concept of type guards, explore the different types of type guards that TypeScript offers, and learn how to use them in practical scenarios.
TypeScript's Infer Keyword: Unlocking Type Information
Updated on · 7 min read|TypeScript's infer keyword is a powerful tool for extracting type information from other types. In this article, we'll explore how to use it to create more flexible and reusable type definitions.
Introduction to Type Inference In TypeScript
Updated on · 7 min read|Type inference in TypeScript helps in determining variable or expression types based on its value when it's not explicitly specified. When TypeScript can infer the type of a variable, there is no need to annotate the variable with a type, which can make the code cleaner and easier to read.

TypeScript: Typing Form Events In React
Updated on · 9 min read|Handling events in React is very close to how the events on DOM elements are handled. The biggest difference is, however, that React wraps the native DOM events into SyntheticEvent, making them behave slightly differently than the native events. Consequently, typing form events in React is not the same as native events. In this post, we'll see how to type form events in React on the example of a simple component as well as discuss the most common pitfalls.
