Some drops of JavaScript

Some drops of JavaScript

The reason why

This book collects practical, unknown, or underrated JavaScript functions or things discovered, used, and learned during daily JavaScript use.

When using JavaScript frameworks/libraries daily (like React, Vue, Angular, and Svelte), sometimes one needs to catch up on the language’s power and the basic functionalities the JavaScript core provides. I notice that I usually look at the framework documentation or find a package in NPM for the system, array, and string functions instead of using the core functionalities provided by the language.

While I wrote this HTML book, I also wrote some scripts to better understand the functions’ behavior. You can find these examples in the examples directory at https://github.com/roberto-butti/some-drops-of-javascript.

Requirements

The code used in this book is tested with Bun (latest) and Node.js (LTS).

Bun is a JavaScript runtime, package manager, bundler, and test runner built from scratch using the Zig programming language. Jarred Sumner designed it as a drop-in replacement for Node.js. Bun uses JavaScriptCore as the JavaScript engine, unlike Node.js and Deno, which both use V8. The official website is: https://bun.sh/ .

Node.js is an open-source, cross-platform JavaScript runtime environment. You can obtain it on the official https://nodejs.org/ website.

Continuous release

I was thinking of printing this book, but I think it is not eco-friendly, and a book about development could be improved daily regarding spellchecking, content, and examples. I expect to adopt the same approach in the software with the CI/CD, with a continuous release of the book.

Releases:

  • W.I.P. the 1.0.0 version has not yet been released: writing… ;

The book is a Work in Progress, and the list of currently covered functions is in the list-of-functions.md file
