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.

Then, you learned about the DOM, an API to represent an HTML or XML document as a tree structure, where each tag or text is a node on the tree. You also learned how to perform the following actions:

  • Accessing nodes:

    • Using parent/child relationship properties, such as parentNode, childNodes, firstChild, lastChild, nextSibling, and previousSibling

    • Using getElementsById(), getElementsByTagName(), getElementsByName(), and querySelectorAll()

  • Modifying nodes:

    • Using innerHTML or innerText/textContent

    • Using nodeValue or setAttribute(), or just using attributes as object properties

  • Removing nodes with removeChild() or replaceChild()

  • Adding new ones with appendChild(), cloneNode(), and insertBefore...
