Do you need a tool to write safer, more maintainable JavaScript code? Learn TypeScript with online courses delivered through edX.
What is TypeScript?
TypeScript is a statically typed programming language that extends JavaScript, adding a layer of static type checking to enhance code reliability and maintainability. It allows developers to explicitly specify data types for variables, function parameters, and return values, catching type-related errors during development rather than at runtime. This leads to more robust, bug-resistant code, especially in large-scale projects.
TypeScript supports object-oriented programming concepts like classes and interfaces, making it easier to build complex software systems. It is also compatible with JavaScript, allowing developers to gradually introduce it into existing JavaScript projects.
Major libraries and frameworks, such as Angular and React, offer TypeScript support. The language offers a balance between the flexibility of JavaScript and the safety of static typing, thereby enhancing productivity and code quality in modern software development.1
