What parts does javascript consist of? And what is the role of each part?

JavaScript components and their roles: Core (ECMAScript): Interprets and executes code, manipulates DOM and browser APIs. Extension API: Interact with HTML documents and the web, create graphics, control media playback. Frameworks and libraries: Provide application structure and pre-written functionality that simplify specific tasks.

JavaScript components and their functions

JavaScript is composed of the following main parts:

1. Core (ECMAScript):

• Core engine: responsible for interpreting and executing JavaScript code.
• Object model: Provides objects and methods for operating DOM (Document Object Model) and browser API.
• BOM (Browser Object Model): Allows JavaScript to access the browser environment such as windows, documents, and navigation.

2. Extension API (Application Programming Interface):

• DOM API: used to interact with HTML and XML documents.
• Network API: used to send network requests, receive responses and manipulate data.
• canvas API: used to create and manipulate graphics.
• Media API: used to control audio and video playback.

3. Frameworks and Libraries:

• Frameworks (e.g. React, Angular): Provide structures and tools for building web applications.
• Libraries (e.g. jQuery, Lodash): Provide pre-written functionality to simplify specific tasks.

The role of each part

• Core: Provides the foundation of JavaScript, allowing us to write and execute code.
• Extension API: Allows JavaScript to interact with external environments such as browsers, networks, and devices.
• Frameworks and libraries:Simplify the development of web applications and improve code reusability and maintainability.
