JavaScript today must interact with data-intensive APIs and networks. The solution is a program that can work asynchronously instead of finishing tasks in order. In modern JavaScript, instead of callbacks you'll use promises to improve your application's performance and responsiveness. JavaScript features introduced in ES2020, ES2021, and ESNext like Promise.allSettled(), Promise.any(), and top-level await help you develop small, fast, low-profile applications. With the AbortController API, cancel a pending async request before it has completed. Modern Asynchronous JavaScript gives you an arsenal of tools to build programs that always respond to user requests, recover quickly from difficult conditions, and deliver maximum performance. Applications today must work with information on remote servers, and users expect a quick response to complex interactions at all times, whether on a high-speed 5G cellular network or slow public WiFi. JavaScript provides developers with advanced tools to coordinate the asynchronous parts of their code efficiently and deliver responsive programs. Faster applications equal happier users, which is the promise of asynchronous JavaScript. With Modern Asynchronous JavaScript you'll learn techniques for managing your async code. Features like ES2021 Promise.any() allow you to safeguard your async code from external issues that are out of your control like server downtime. You'll discover secret weapons like top-level await to initialize resources, define dependency paths dynamically, and load dependencies with a fallback implementation. You'll even learn to how to set a time limit for async requests and react if they take too long to complete. Fast, reliable applications are a must in today's world, where users demand increasingly greater amounts of data on mobile devices. Asynchronous programming may require more cautious planning than synchronous programming but the outcome is rewarding. Asynchronous JavaScript allows you to write code that is nimble but reliable, leading to programs that load faster, respond quicker, and most importantly that you can trust to function properly. What You Need: You'll need an intermediate level of JavaScript programming skills and a browser that supports features from ES2020, ES2021, and ESNext.
JavaScript Functional Programming Made Simple: A Practical Guide with Examples
Master the art of functional programming with "JavaScript Functional Programming Made Simple: A Practical Guide with Examples" by William E. Clark. This comprehensive guide serves as an indispensable resource for developers of all proficiency levels who wish to deepen their understanding of functional programming principles and apply them within the JavaScript ecosystem. Through clear explanations and practical examples, the book elucidates foundational concepts such as pure functions, immutability, and higher-order functions, equipping readers with the skills to write concise, efficient, and maintainable code. Structured to progressively build knowledge, the book starts with an introduction to the core tenets of functional programming, juxtaposing them with other paradigms to emphasize their unique advantages. Readers are guided through setting up a development environment tailored for functional programming, including tool recommendations and best practices for version control. The exploration continues with in-depth treatment of closures, recursion, and asynchronous programming, each complemented by illustrative examples that demonstrate real-world applications. The latter sections delve into advanced topics, such as monads, transducers, and lazy evaluation, offering strategies to optimize performance and manage data transformations effectively. A review of popular libraries and tools enhances the learning experience, providing practical avenues to implement functional programming techniques in everyday projects. This book not only serves as a detailed introduction for beginners but also as a valuable reference for experienced programmers seeking to enhance their functional programming prowess in JavaScript.
