TypeScript2 min readInterfaces in TypeScript define contracts for objects, specifying the shape and behavior expected. This guide covers how to create interfaces, use optional properties, and apply readonly modifiers for safer code.
TypeScript2 min readObjects are fundamental in TypeScript. This guide covers how to define object types using inline annotations, handle nested objects, and work with object literals to ensure type safety and clarity.
TypeScript3 min readArrow functions in TypeScript and JavaScript have distinct behavior with the 'this' context compared to regular functions. This guide explains context binding, the differences between arrow and regular functions, and when to use each for optimal results.

TypeScript3 min readFunction overloading allows you to define multiple function signatures for a single implementation in TypeScript. This guide covers how to write overloaded functions, the implementation signature, and practical use cases to improve type safety and clarity.
TypeScript2 min readFunctions often need flexibility in their parameters. TypeScript provides optional, default, and rest parameters to make function signatures adaptable while maintaining type safety. This guide covers how to use these features effectively.
TypeScript3 min readFunctions are the building blocks of any program. In TypeScript, typing function parameters and return values helps catch errors early and improves code readability. This guide covers function signatures, typing parameters and returns, void functions, and implicit return types.
TypeScript13 min readType assertions tell TypeScript to trust your judgment about a value's type. While they're powerful tools for working with DOM elements, API responses, and type narrowing, they can also bypass type safety if misused. This guide covers the as syntax, angle-bracket syntax, when to use assertions safely, and the crucial difference between TypeScript assertions and runtime type casting. Learn to wield this tool responsibly while maintaining type safety in your applications.
TypeScript15 min readTypeScript has three special types that handle edge cases: any (the escape hatch), unknown (the type-safe alternative), and never (for impossible values). Understanding when and how to use these types is crucial for writing safe yet flexible TypeScript code. This guide covers the differences between these types, shows you how to work with unknown safely, and demonstrates how never enables exhaustive type checking and prevents runtime errors. Learn to use these types effectively while maintaining type safety.
