- A tree-like data structure that represents the structure of an HTML document
- The ability to manipulate HTML elements, styles and events
- Used to create and modify web content
4. Asynchronous programming
- Event loops and event listeners
- Callback functions and Promise
- Used to handle asynchronous operations
5. Modularization
- CommonJS, AMD and ES modules
- Organize code into reusable modules
- Promote code sharing and maintenance
6. Development tools
- Debugging 7. Frameworks and Libraries
- Web frameworks such as React and Vue.js
Utility libraries such as jQuery and Lodash
They provide pre-built components and functions to simplify JavaScript development
Together these core components make up JavaScript, making it a powerful language capable of building dynamic and interactive applications.
