TypeScript is an open-source programming language developed and maintained by Microsoft. It is a superset of JavaScript, which means that all valid JavaScript code is also valid TypeScript code. TypeScript adds optional static typing, classes, interfaces, and other features to JavaScript to improve code quality, maintainability, and scalability. In this article, we'll explore how TypeScript is an optionally statically typed language, what that means for developers, and how it can benefit them in their projects. What is Optional Static Typing? Static typing is a programming language feature that allows developers to define data types for variables, function parameters, and function ... Read More

TypeScript, a superset of JavaScript, offers static typing capabilities that enhance code quality and catch errors during compilation. To fully leverage TypeScript's static typing features, it's crucial to have type definition files (.d.ts) for external JavaScript libraries and modules used in projects. These type definition files describe the types and interfaces exposed by the external entities, enabling the TypeScript compiler to understand their shape and behaviour. In this article, we'll explore the step-by-step process of creating custom TypeScript type definition files, empowering developers to benefit from static typing in their projects. Prerequisites Type definition files (.d.ts) serve as an interface ... Read More

TypeScript, an extension of JavaScript, introduces modules as a means to structure and organize code effectively. Modules play a vital role in developing scalable and maintainable applications by enabling code encapsulation and reusability. TypeScript supports two types of modules: internal (namespaces) and external (ES modules). In this article, we will delve into the differences between internal and external modules in TypeScript, exploring their characteristics and impact on code organization and sharing within a project. Internal Modules Internal modules, also known as namespaces, serve as logical containers within a single file to group related code elements together. They offer benefits such ... Read More

TypeScript is a superset of JavaScript that adds optional static typing to the language. This means that TypeScript allows developers to specify the types of variables, function parameters, and function return values. This feature helps to catch errors early in the development process and makes the code more robust. In TypeScript, type annotations are used to specify the types of variables, function parameters, and function return values. In this tutorial, we will explore different scenarios where type annotations are used in TypeScript and how they can help developers write better code. Declaring Variables With Type Annotations Syntax The syntax to ... Read More

TypeScript is a popular programming language widely used for developing large-scale applications. It is a superset of JavaScript and adds optional static typing, interfaces, and generics to the language. When working with TypeScript, it is crucial to have a smooth development workflow that includes automatically compiling .ts files with real-time changes. In this article, we will explore the different tools and techniques that can be used to achieve this. Why Automatically Compile TypeScript Files? When working on a TypeScript project, developers often make changes to the .ts files. After making changes, they must compile these files to get the corresponding ... Read More
