Introduction to JavaScript
JavaScript is a scripting language that is primarily used to create dynamic and interactive web pages.
It can be used to create animations, validate forms, and add interactivity to web pages.
It is a high-level language and does not require compilation before execution.
Variables and Data Types
Variables are used to store values in JavaScript.
There are different data types in JavaScript, including strings, numbers, Booleans, arrays, and
objects.
JavaScript uses dynamic typing, which means that the data type of a variable can change at runtime.
Control Structures
Control structures are used to control the flow of execution in JavaScript.
Examples of control structures include if/else statements, switch statements, and loops.
Loops in JavaScript include for, while, and do-while loops.
Functions
Functions are reusable blocks of code that perform a specific task.
They are declared using the function keyword followed by a name, parameter list, and a block of
code.
Functions can return values using the return keyword.
Arrays and Objects
Arrays are used to store collections of values in JavaScript.
They are declared using square brackets and can store values of any data type.
Objects are used to store key-value pairs in JavaScript.
They are declared using curly braces and can have properties and methods.
