Overview of this book

JavaScript is an object-oriented programming language that is used for website development. Web pages developed today currently follow a paradigm that has three clearly distinguishable parts: content (HTML), presentation (CSS), and behavior (JavaScript). JavaScript is one important pillar in this paradigm, and is responsible for the running of the web pages. This book will take your JavaScript skills to a new level of sophistication and get you prepared for your journey through professional web development. Updated for ES6, this book covers everything you will need to unleash the power of object-oriented programming in JavaScript while building professional web applications. The book begins with the basics of object-oriented programming in JavaScript and then gradually progresses to cover functions, objects, and prototypes, and how these concepts can be used to make your programs cleaner, more maintainable, faster, and compatible with other programs/libraries. By the end of the book, you will have learned how to incorporate object-oriented programming in your web development workflow to build professional JavaScript applications.

Lets solve the following exercise:

  1. Look at the following code:

            function F() { 
              function C() { 
               return this; 
              return C(); 
            var o = new F(); 

    Does the value of this refer to the global object or the object o?

  2. What's the result of executing this piece of code?

            function C(){  
              this.a = 1; 
              return false; 
            console.log(typeof new C()); 
  3. What's the result of executing the following piece of code?

            > c = [1, 2, [1, 2]]; 
            > c.sort(); 
            > c.join('--');  
            > console.log(c);  
  4. Imagine the String() constructor didn't exist. Create a constructor function, MyString(), that acts like String() as closely as possible. You're not allowed to use any built-in string methods or properties, and remember that the String() doesn't exist. You can use this code to test your constructor...
