A Guide to Helpers, Collections And More
About the Book
The Laravel framework contains many useful helper functions, features and utility classes (such as Collections) - not all of these are well known. This book exposes these helper utilities to encourage accelerated application development using the Laravel framework (version 5.3). Through the Laravel Companion you will learn about collections, facades, application helper functions, request and URL helper functions and much, much more.
If you've ever thought there "has to be an easier way" - there probably is in the form of a helper utility.

C++20 is the next big C++ standard after C++11. As C++11 did it, C++20 changes the way we program modern C++. This change is, in particular, due to the big four of C++20: ranges, coroutines, concepts, and modules.
The book is almost daily updated. These incremental updates ease my interaction with the proofreaders.
