Learn Bosque Programming

By: Sebastian Kaczmarek, Joel Ibaceta

Overview of this book

Bosque is a new high-level programming language inspired by the impact of structured programming in the 1970s. It adopts the TypeScript syntax and ML semantics and is designed for writing code that is easy to reason about for humans and machines. With this book, you'll understand how Bosque supports high productivity and cloud-first development by removing sources of accidental complexity and introducing novel features. This short book covers all the language features that you need to know to work with Bosque programming. You'll learn about basic data types, variables, functions, operators, statements, and expressions in Bosque and become familiar with advanced features such as typed strings, bulk algebraic data operations, namespace declarations, and concept and entity declarations. This Bosque book provides a complete language reference for learning to program with Bosque and understanding the regularized programming paradigm. You'll also explore real-world examples that will help you to reinforce the knowledge you've acquired. Additionally, you'll discover more advanced topics such as the Bosque project structure and contributing to the project. By the end of this book, you'll have learned how to configure the Bosque environment and build better and reliable software with this exciting new open-source language.

Chaining in Bosque

Alright, now it is time to introduce a fresh concept! In Bosque, there is a special none value that is basically – as the name suggests – a value representing no value. It is pretty similar to the null value from other languages, or – in some cases – to undefined if you are familiar with JavaScript.

Every programmer who has faced the challenge of handling such no-value values knows how hard is it, especially when we need to perform chaining where one of the middle components may be none (or null). I'm pretty sure you already know what chaining is but in case you don't, it is worth reminding that chaining is the process of accessing values or calling methods that are nested deep inside each other. An example of such a nested structure can be seen in the following example:

let merchCategories = {
    accessories = {
        kitchen = {
     ...
