Javascript can be used for a variety of purposes beyond just front-end web development. Some of the main things you can do with Javascript are:
You can ask a web server for data and then display that data on your page.
You can add, modify, or remove page text, HTML tags, and even CSS properties.
You can display messages to the user and ask the user for information.
You can "listen" for and then perform an action based on events such as visitors clicking their mouse or pressing a key.
You can send the user's browser to another page.
You can validate the values in a form before submitting it to the server. For example, you can make sure that certain fields are filled in.
You can collect, save, and retrieve data for each of your users, such as site customization.
Frontend web development: Javascript is typically used to add interactivity and dynamic functionality to web pages. This includes DOM manipulation, event handling, and AJAX requests.
Backend web development with Node.js: Node.js allows you to run Javascript on the server side. You can use Node.js to build APIs, web servers, and backend services.
Mobile app development: Javascript frameworks like React Native and NativeScript allow you to build native mobile apps using Javascript.
Desktop app development: With frameworks like Electron and NW.js, you can build cross-platform desktop apps using HTML, CSS and Javascript.
Game development: There are Javascript game frameworks like Phaser and Babylon.js that make it easy to create 2D and 3D games.
Machine learning and AI: Libraries like TensorFlow.js allow you to do machine learning and train neural networks in Javascript.
Data visualization: Libraries like D3.js make it easy to create interactive charts, graphs and maps using Javascript.
Internet of Things: Javascript is a good choice for developing apps for connected devices and the Internet of Things.
Embedded device development: Javascript can be used to create apps for small devices like microcontrollers.
Conclusion-
So in summary, while Javascript was originally created for frontend web development, it has evolved into a versatile language that can be used for a wide range of tasks - from web to mobile, desktop, IoT, AI and beyond. The possibilities are endless with Javascript!
