Main components of JavaScript

JavaScript is a powerful programming language that is widely used for the Web , mobile applications and server-side environments provide interactivity and dynamics. Its key components include:

1. Core syntax

• Variables and data types

• 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

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.
