What is JavaScript:
Scripting or Programming Language: JavaScript is primarily a scripting language but is also considered a programming language due to its extensive functionality and capabilities.

Java and JavaScript Are Not the Same: Despite the similar names, Java and JavaScript are entirely different languages with different use cases and syntax.

JavaScript Executes in User's Browser: JavaScript code is executed in the user's web browser, allowing for dynamic content and interactions within web pages.

JavaScript is also Known as JS: Commonly abbreviated as JS.

JavaScript is a Dynamic Programming Language: JavaScript is dynamic, meaning variables are loosely typed and types can change at runtime.

JS is Case-Sensitive: JavaScript is case-sensitive, meaning that var, Var, and VAR would be considered different identifiers.

JS is an Interpreted Language (Line by Line Execution): JavaScript is interpreted, meaning code is executed line by line, which allows for immediate feedback during development.

Interpreted Languages: Examples include JavaScript and Python.

Compiled Languages: Examples include C and Java, where code is compiled into machine language before execution.

DOM (Document Object Model) Manipulation: JavaScript can interact with and manipulate the DOM to dynamically update the content, structure, and style of web pages.

Calculation: JavaScript can perform various calculations, from simple arithmetic to complex mathematical operations.

Form Validation: JavaScript can validate user input in forms before it is submitted to the server, improving user experience and reducing server load.

AJAX-API Integration: JavaScript can make asynchronous requests to servers using AJAX, allowing for dynamic content updates without reloading the page, and can interact with various APIs.

Object-Oriented Programming Language (OOP): JavaScript supports object-oriented programming concepts, including objects, inheritance, encapsulation, and polymorphism.

Overall, JavaScript is a versatile and powerful language essential for modern web development, providing the tools needed to create interactive, dynamic, and responsive user experiences.
