Key differences between TypeScript and JavaScript
Characteristic | TypeScript | JavaScript |
---|---|---|
Syntax | TypeScript is a superset of JavaScript, so it has the same syntax as JavaScript with some additional features. | JavaScript has a simple and flexible syntax that is easy to learn and use. |
Paradigm | TypeScript is an object-oriented programming language that supports both object-oriented and functional programming paradigms. | JavaScript is a multi-paradigm language that supports object-oriented, functional, and imperative programming paradigms. |
Typing | TypeScript is a statically typed language that allows developers to define types for variables, functions, and objects. | JavaScript is a dynamically typed language that does not require developers to define types for variables, functions, and objects. |
Performance | TypeScript can improve the performance of JavaScript applications by catching errors at compile-time and optimizing code at runtime. | JavaScript can be slower than TypeScript because it is interpreted at runtime and errors are caught at runtime. |
Libraries and frameworks | TypeScript has access to all the libraries and frameworks available for JavaScript, as well as its own set of libraries and frameworks. | JavaScript has a vast ecosystem of libraries and frameworks that are widely used and supported. |
Community and support | TypeScript has a growing community of developers and is supported by Microsoft. | JavaScript has a large and active community of developers and is supported by all major web browsers. |
Learning curve | TypeScript has a steeper learning curve than JavaScript because it requires developers to learn new concepts such as types and interfaces. | JavaScript has a relatively low learning curve and is easy to get started with. |
