What is Javascript?
JavaScript is a versatile, high-level programming language primarily used for creating interactive web content. It enables dynamic behaviour on web pages, handling user interactions, manipulating HTML/CSS, and facilitating both client-side and server-side development through frameworks like Node.js. JavaScript's widespread adoption and powerful capabilities make it a cornerstone of modern web development.
What is Typescript?
TypeScript is an open-source programming language developed by Microsoft. It is a superset of JavaScript that adds static typing to the language, allowing developers to define types for variables, function parameters, return types, and more. This helps catch errors during development and provides better tooling support for large-scale applications. TypeScript compiles down to plain JavaScript and offers features like interfaces, enums, generics, and advanced type inference.
What is an Interface?
Interfaces in TypeScript define the structure or shape of an object by specifying the properties it should have along with their types. They provide a way to define contracts within your code, ensuring that certain objects adhere to a specific structure. Interfaces promote code reusability and maintainability by allowing different parts of your codebase to work together based on shared structures defined by these interfaces.
What is Type Inference?
Type inference is a feature in TypeScript that allows the compiler to automatically deduce the data types of variables, parameters, and other entities based on their usage and initialization values. TypeScript's type inference system analyzes how values are assigned and used within the code to determine their types. This feature reduces the need for explicitly specifying types everywhere and helps in writing cleaner, more concise code while still ensuring type safety.
