Mastering JavaScript Functional Programming

This is the code repository for Mastering JavaScript Functional Programming, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.

About the Book

Functional programming is a programming paradigm for developing software using functions. Learning to use functional programming is a good way to write more concise code, with greater concurrency and performance. The JavaScript language is particularly suited to functional programming.

This book provides comprehensive coverage of the major topics in functional programming with JavaScript to produce shorter, clearer, and testable programs.

You’ll delve into functional programming; including writing and testing pure functions, reducing side-effects, and other features to make your applications functional in nature.

Specifically, we’ll explore techniques to simplify coding, apply recursion for loopless coding, learn ways to achieve immutability, implement design patterns, and work with data types.

By the end of this book, you’ll have developed the JavaScript skills you need to program functional applications with confidence.

Instructions and Navigation

All of the code is organized into folders. Each folder starts with a number followed by the application name. For example, Chapter02.

The code will look like the following:

{
 if( (result != VK_SUCCESS) || 
    (extensions_count == 0) ) { 
  std::cout << "Could not enumerate device extensions." << std::endl; 
  return false;
}

Chapter 7, question 7-1 confusion

Hello, I went over the 7th chapter and there is a question that made me a little confused.

7.1. Sum as you will: The following exercise will help you understand some of
the concepts we dealt with in this chapter, even if you solve it without using
any of the functions we looked at. Write a sumMany() function that lets you
sum an indeterminate quantity of numbers, in the following fashion. Note that when
the function is called with no arguments, the sum is returned.

let result = sumMany((9)(2)(3)(1)(4)(3)());

The number 9 is not a function, so the error that is immediately being triggered is:

console.log((9)());
               ^

TypeError: 9 is not a function

Is there a typo by any chance? I trying different ways to avoid this error, but not sure if I am doing anything wrong.
