JavaScript Basics

JavaScript is a versatile programming language primarily used for web development. It allows you to create interactive and dynamic web pages. Here's a rundown of some fundamental concepts:

Strings

Strings are sequences of characters used to represent text. In JavaScript, strings can be created using single quotes ('), double quotes (")

Arrays

Arrays are used to store multiple values in a single variable. Each value (also called an element) in an array has an index, with the first element having an index of 0.

Arrays come with many useful methods, such as .push(), .pop(), .shift(), .unshift(), and .splice().

Objects

Objects are used to store collections of key-value pairs. Each key is a string (or symbol) and each value can be any type, including other objects and functions.
