JavaScript: Understanding the Weird Parts (Udemy)

What you'll learn

• Grasp how Javascript works and its fundamental concepts

• Write solid, good Javascript code

• Understand advanced concepts such as closures, prototypal inheritance, IIFEs, and much more.

• Drastically improve your ability to debug problems in Javascript.

• Avoid common pitfalls and mistakes other Javascript coders make

• Understand the source code of popular Javascript frameworks

• Build your own Javascript framework or library

Requirements

• Basic Javascript knowledge (variables, loops, and basic functions - that's all the course expects you to know!)

• A browser and text editor

Description

Javascript is the language that modern developers need to know and know well. Knowing Javascript well will get you a job, and enable you to build quality web and server applications.

NOTE: This course includes information on ECMAScript 6 (ES6) the next version of Javascript!

In this course, you will gain a deep understanding of Javascript, learn how Javascript works under the hood, and how that knowledge helps you avoid common pitfalls and drastically improve your ability to debug problems. You will find clarity in the parts that others, even experienced coders, may find weird, odd, and at times incomprehensible. You'll learn the beauty and deceptive power of this language, which is at the forefront of modern software development today.

This course will cover such advanced concepts as objects and object literals, function expressions, prototypical inheritance, functional programming, scope chains, function constructors (plus new ES6 features), immediately invoked function expressions (IIFEs), call, apply, bind, and more.

We'll take a deep dive into the source code of popular frameworks such as jQuery and Underscore to see how you can use your understanding of Javascript to learn (and borrow) from other people's good code.

Finally, you'll learn the foundations of how to build your Javascript framework or library.

What you'll learn in this course will make you a better Javascript developer, and improve your abilities in AngularJS, NodeJS, jQuery, React, Ember, MongoDB, and all other Javascript-based technologies!

Learn to love JavaScript and code well in it.

NOTE: In this course, you'll also get a downloadable source code. You will often be provided with 'starter' code, giving you the base on which to start writing your code, and 'finished' code to compare your code to.

Who this course is for:

• Those with basic Javascript skills who wish to improve

• Experienced coders coming from other programming languages

• New and experienced Javascript coders who want to deepen their understanding of the language

• Anyone who has found concepts just as object prototypes, closures, and other advanced concepts difficult to learn

• Those who have suffered surprising errors while writing Javascript, and want to learn why and how to avoid them

• Those interested in building their own frameworks or being better able to learn from the source code of other well-known frameworks and libraries

JavaScript Introduction (Edx)

About this course

This course is part of W3C's "Front-End Web Developer" Professional Certificate.

JavaScript lets you add interactive features to your Web sites, including dynamically updated content, controlled multimedia, animated images, and much more. Developed in partnership between W3C and the University of Côte d'Azur, this introductory course has been designed to help Web developers gain an understanding of the basic concepts of the language. We present JavaScript best practices using many interactive examples, some of which are demonstrated in live coding videos.

We use JavaScript in the Web browser. Why JavaScript is worth your time:

• HTML5, CSS and JavaScript are the “classic three” for developers and designers;

• It adds interactivity to your Web sites;

• It is powerful, easy to learn, and quick to write;

• It has great tools (editors, runtimes, lint tools, browsers, and third-party libraries) as well as great online support through plenty of active open-source communities.

At the end of the course, we expect you to be able to read the source code of any JavaScript example found on the Web, learn from it, tweak it, and even – why not? – start contributing to open-source JavaScript projects.

What you'll learn

• How to add JavaScript code in your Web site/Web app, and how to debug it

• How to make interactive Web sites through the DOM API

• How to change the CSS styles of HTML5 elements from JavaScript

• How to deal with HTML5 forms

• How to make basic graphics and animations using the HTML5 canvas
