Basics of Javascript.

Basics of javascript

 JavaScript is a high-level, interpreted programming language used primarily for front-end web development. It is a dynamic, untyped language with first-class functions and objects.

Basics of JavaScript include:

(1)

Variables: Used to store data and can be declared using the "var", "let", or "const" keywords.

(2)

Data Types: JavaScript has dynamic types, including Number, String, Boolean, Object, Null, and Undefined.

(3)

Operators: Used to perform operations on variables and values, such as assignment (=), arithmetic (+,-,*,/), comparison (==, ===, !=, !==, >, <, >=, <=), and logical (&&, ||, !).

(4)

Conditional statements: Used to execute code based on conditions, such as if-else and switch.

(5)

Loops: Used to repeat a block of code multiple times, such as for, while, and do-while loops.

(6)

Functions: Used to group code and can be reused throughout the code. Functions can accept parameters and return values.

(7)

Objects: Used to store data as key-value pairs and can be used to represent real-world objects.

(8)

Arrays: Used to store ordered collections of data and can be accessed by index.

(10)

Event handling: Used to respond to user actions and manipulate the DOM.

These are the basics of JavaScript, but the language has much more to offer and continues to evolve.
