A better way to learn JavaScript - Building Mini Apps
A better way to learn JavaScript - Building Mini Apps
Let's build some mini apps in JavaScript
About the Book
This book is the fourth in my 5-book series on JavaScript.
In Book 1, we learned about JS basics, with an in-depth coverage of foundations.
In Book 2, we examined all the built-in objects in depth, including their properties, methods, and constructors.
In Book 3, we went through a bunch of code snippets, simple "sub-programs" that dealt with a specific issue, such as emulating a pair of dice, or capitalizing each first letter in a sentence.
In this book, Building Mini Apps, we're continuing from simple snippets from Book 3, and we're using all the things we've learned so far to build some specific "mini apps": standalone solutions to various issues.
