JS Tutorial

JavaScript is widely known as the most popular scripting language used on the client side, referring to scripts that run within web browsers. Its main purpose is to add interactivity and dynamic effects to web pages by manipulating the content fetched from web servers.

Originally named LiveScript by Netscape in the mid-1990s, it was later renamed JavaScript in 1995 and became an ECMA standard in 1997. Nowadays, JavaScript is the standard scripting language for client-side web applications, supported by nearly all web browsers such as Google Chrome, Mozilla Firefox, Apple Safari, and others.

JavaScript is an object-oriented language, sharing some syntax similarities with Java, but it's essential to understand that JavaScript is not related to Java in any way.

ECMA (European Computer Manufacturers Association) oversees the maintenance of JavaScript, known formally as ECMAScript. The most recent significant iteration of this standard is ECMAScript 6, often abbreviated as ES6.

Tip: Our JavaScript tutorial is crafted to lead you through learning the basics of the JavaScript scripting language, from simple to advanced topics, step by step. If you're a beginner, start with the fundamentals and progress gradually by learning a little each day.

What JavaScript Can Do

JavaScript offers a wide range of capabilities:

You can modify the content of a web page by adding or removing elements.
You can adjust the style and position of elements on a web page.
You can track events like mouse clicks, hovers, etc., and respond to them.
You can manage transitions and animations.
You can create alert pop-ups to show information or warning messages to users.
You can execute operations based on user inputs and display the results.
You can validate user inputs before submitting them to the server.

This list serves as a starting point; there are many more exciting possibilities to explore with JavaScript. Detailed insights into these topics will be covered in upcoming chapters.

What You'll Learn

This JavaScript tutorial series thoroughly covers essential programming concepts, including data types, operators, variable creation and usage, output generation, code structuring for decision-making and looping, string and array manipulation, function definition and invocation, and more.

After mastering the basics, the tutorial progresses to more advanced topics, explaining concepts like objects, the Document Object Model (DOM) and Browser Object Model (BOM), utilization of native JavaScript objects such as Date and Math, along with performing type conversions.

Lastly, you'll delve into advanced concepts like event listeners, event propagation, method borrowing from other objects, JavaScript's hoisting behavior, JSON data encoding and decoding, and an extensive overview of new features introduced in ECMAScript 6 (or ES6).

Tip: Each chapter in this tutorial contains numerous real-world examples for you to try and test using an online editor. These examples will enhance your understanding of the concepts and include clever solutions, helpful tips, and important notes.
