JavaScript is a high-level, interpreted programming language that is primarily known for its use in web development. It allows developers to create dynamic and interactive content on websites. Client-Side Scripting: 1. JavaScript is mainly used for client-side scripting, which means it runs in the user's web browser and helps to create dynamic and interactive web pages. Object-Based: 2. JavaScript is an object-based scripting language. It uses objects and their properties to create and manipulate data. Event-Driven Programming: 3. JavaScript is often used in conjunction with HTML and CSS to respond to user actions (e.g., clicks, form submissions) and modify the content or appearance of a web page accordingly. Cross-Platform: 4. JavaScript is supported by all major web browsers, making it a cross-platform language. This enables consistent behavior across different browsers. Asynchronous Programming: 5. JavaScript supports asynchronous programming, allowing developers to handle tasks like fetching data from a server without blocking the execution of other code. ECMAScript: 6. The ECMAScript specification standardizes JavaScript and is regularly updated to introduce new features and improvements. JavaScript is often referred to by its ECMAScript version (e.g., ES5, ES6, ES2015, etc.). Dynamic Typing: 7.JavaScript is a dynamically typed language, meaning you don't need to specify the data type of a variable explicitly. The type is determined at runtime. Functions as First-Class Citizens: 8.In JavaScript, functions are treated as first-class citizens, meaning they can be assigned to variables, passed as arguments to other functions, and returned as values from other functions. Libraries and Frameworks: 9.JavaScript has a vast ecosystem of libraries and frameworks that simplify common tasks. Some popular ones include React, Angular, Vue.js (for building user interfaces), and Node.js (for server-side JavaScript). Security: 10.JavaScript has security features that help prevent malicious actions. However, it's crucial for developers to be aware of potential security vulnerabilities and follow best practices. Interoperability: 11.JavaScript can be embedded within HTML documents, making it easy to integrate into existing web pages. It can also communicate with server-side languages like PHP or Python.
