Object-Oriented language: TypeScript encompasses the full range of features characteristic of an object-oriented programming language, including classes, interfaces, inheritance, and modules. With TypeScript, it is possible to develop code for both client-side and server-side applications.
TypeScript is compatible with JavaScript libraries: TypeScript accommodates all JavaScript components. It enables developers to integrate current JavaScript code into TypeScript projects. Consequently, we can effortlessly utilize a variety of JavaScript frameworks, tools, and other libraries.
JavaScript is essentially TypeScript: This indicates that code authored in JavaScript with a valid .js file extension can be transformed into TypeScript by simply altering the extension from .js to .ts, after which it can be compiled alongside other TypeScript files.
TypeScript is versatile: TypeScript is versatile as it can operate on all browsers, devices, and operating systems. It can be executed in any setting that supports JavaScript. It is not limited to any specific virtual machine for its execution.
DOM Manipulation: TypeScript can be utilized for manipulating the DOM to insert or delete elements in a manner akin to JavaScript.
TypeScript is essentially JavaScript: TypeScript code cannot be directly executed by browsers. Any program developed in TypeScript begins with JavaScript and concludes with JavaScript. Therefore, a foundational understanding of JavaScript is required to work with TypeScript. The TypeScript code undergoes compilation, transforming it into its JavaScript counterpart for execution. This transformation process is referred to as Trans-piled. Utilizing the JavaScript code, browsers are able to interpret the TypeScript code and present the results.
Benefits of TypeScript Compared to JavaScript
- TypeScript always highlights errors at compilation time during the time of development, whereas JavaScripTypeScript Tutorials out errors at the runtime.
- TypeScript supports strongly typed or static typing, whereas this is not in JavaScript.
- TypeScript runs on any browser or JavaScript engine.
- Great tooling supports with IntelliSense, which provides active hints as the code is added.
- It has a namespace concept by defining a module.
- TypeScript takes a long time to compile the code.
- TypeScript does not support abstract classes.
- If we run the TypeScript application in the browser, a compilation step is required to transform TypeScript into JavaScript.
