Learning Objectives

• Why JavaScript?
• About JavaScript
• The content available in various tutorials in this series.

• A text editor, in which to write and understand the JavaScript code and
• A web browser.

• Ubuntu Linux OS version 18.04
• Visual Studio Code version 1.45.0 (code editor)
• Firefox web browser

Today, JavaScript is very popular because we can develop

• Web applications
• Mobile applications (Windows, Android and IOS)
• Desktop applications,
• Virtual Reality applications and
• Do a lot more with this language.

Apart from Internet Explorer, Netscape Navigator was the only available browser in the early 90s.

Browsers were supporting only static content with HTML and CSS.

Everyone was using the web to just read information like how we read newspapers.

There was no support for actions in the browser.

So to make the web and browser better, JavaScript was introduced.

Using JavaScript, users were able to interact more on the web.

It is a trademark scripting language specification.

ECMAScript ensures the interoperability of web pages across different web browsers.

Until 2015, there were no proper JavaScript new feature release cycles.

In 2015, massive features were introduced, which were released as ECMAScript 6 popularly called ES6.

From then, every year new features were added and released every year as ES7, ES8, ES9… and so on.

In this tutorial series, we would be covering ES6 and above language standards.

Such as arithmetic, logical, relational and other available operators in JS.

We will also learn how to manipulate DOM elements with the help of the window object.

We will also understand the usage of event listeners on HTML elements.

And, learn about their scopes and hoisting in JS.

We’ll learn how to see the closure scope values in the function and their usage with examples.

Along with that, we will be covering template literals and usage of the spread operator.

Then, we will learn more examples to understand the usage of setTimeout and setInterval.

And, we will even look into some of the advanced array loops like forEach, map and filter.

Also, we’ll learn how to use a promise and its advantages.

Then we’ll see how to chain promise and how to handle multiple promise execution with async-await.

We will learn this with a sample GitHub URL and display in the browser.

And, then it will fetch the repo details of the GitHub user for the entered user input.
