Welcome to JavaScript Course
In this course, you will learn all you need to know about JavaScript.
What is JavaScript?
JavaScript (JS) is a high-level, interpreted programming language that is used to make web pages interactive. It is one of the three core technologies of World Wide Web content production (along with HTML and CSS).
Where it came from?
JavaScript was developed in Netscape Communications and Entertainment, Inc. in collaboration with Sun Microsystems. Brendan Eich, a Netscape employee at the time, created JavaScript in 1995 within a span of just 10 days. Initially named Mocha, it was later renamed to LiveScript and finally JavaScript for marketing reasons, despite sharing only a few syntactic similarities with Java.
Key Features of JavaScript
-
Versatility: JavaScript is known for its versatility as it can be used both on the client side (in web browsers) and on the server side (with the help of Node.js).
-
Interactivity: One of the primary purposes of JavaScript is to enhance user interaction on websites. It allows for the creation of dynamic and responsive web pages.
-
Event-Driven: JavaScript is event-driven, meaning it can respond to different events like user actions (clicks, keypresses, etc.) and modify the content accordingly.
-
Object-Oriented: JavaScript is an object-oriented language, which means it works with objects, properties, and methods, providing a structured approach to programming.
-
Asynchronous Programming: JavaScript supports asynchronous programming, enabling tasks to be performed in the background without blocking the main program execution.
How JavaScript Works
JavaScript is primarily executed by web browsers, interpreting the code and manipulating the Document Object Model (DOM) of a webpage. This interaction allows for dynamic changes to the content, structure, and style of the page, providing a more engaging user experience.
Prerequisites for this Course
To make the most out of this course, it's recommended to have a basic understanding of HTML and CSS. Familiarity with programming concepts will also be beneficial, but this course is designed to accommodate beginners.
