Key differences between TypeScript and JavaScript

CharacteristicTypeScriptJavaScript
SyntaxTypeScript 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.
ParadigmTypeScript 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.
TypingTypeScript 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.
PerformanceTypeScript 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 frameworksTypeScript 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 supportTypeScript 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 curveTypeScript 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.
