This book is not a programming course for JavaScript. It is not even an introduction to programming with this language. It is a book containing solutions. How did that go again? How can I sort an array by the length of its elements? Or how do I measure how long a function takes to run? How do I give all my strings the same length? How do I calculate the number of days between two dates? Just a few of the questions you come across when programming. This book provides answers to many of those questions. More than 500 short tips that quickly solve small problems Each tip shows an example program. Often, there is a brief explanation given that shows how the solution works. Outputs are displayed through an alert on the screen or in the console. Sometimes there are multiple solutions for the same problem. This book shows them, so you have the option to choose the one that fits your programming style best. Not only beginners but also advanced JavaScript developers will discover new things in this book.
