Where Javascript Runs?

JavaScript can run on several different platforms, depending on the context in which it is being used. Here are some of the common platforms where JavaScript runs:

1. Web Browsers: JavaScript is primarily used within web browsers, running in response to events such as user interactions or web page loading. All modern web browsers, such as Chrome, Firefox, Safari, and Edge, have built-in JavaScript engines that interpret and execute JavaScript code.
2. Server-Side Platforms: JavaScript can also run on server-side platforms such as Node.js, which allows developers to use JavaScript for server-side programming. This platform provides a runtime environment for executing JavaScript outside of the browser, allowing developers to create scalable and performant server-side applications.
3. Mobile Applications: JavaScript can be used to build mobile applications using frameworks such as React Native. This allows developers to create cross-platform mobile applications with a single codebase.
4. Desktop Applications: JavaScript can also run on desktop applications using frameworks such as Electron. This allows developers to create cross-platform desktop applications with a single codebase.
5. IoT Devices: JavaScript can be used to develop applications for IoT devices, such as smart home devices and wearable technology.

In addition to these platforms, JavaScript can also run on other platforms such as game engines, embedded systems, and more. Its versatility and popularity make it a widely used programming language in many different contexts.
