JS-библиотеку htmx воспринимают как средство, которое спасает интернет от одностраничных приложений. Всё дело в том, что React поглотил разработчиков своей сложностью (так говорят), а htmx предлагает столь желанное спасение. Создатель htmx, Карсон Гросс, иронично объясняет эту динамику библиотеки так : Нет, здесь у нас диалектика Гегеля: • тезис : традиционные многостраничные приложения, • антитезис : одностраничные приложения, • синтез (возвышенная форма): гипермедиа-приложения с островками интерактивности.

Ни один разработчик не застрахован от убедительных методов хакеров. Недавно исследователями из PolySwarm было зафиксировано несколько случаев изощрённых кибератак с техниками социальной инженерии, направленных на разработчиков программного обеспечения.

Фреймворк Angular используется при создании SPA и предлагает большое количество инструментов как для создания, непосредственно, элементов интерфейса, так и CLI для создания и управления структурой файлов, относящихся к приложению. Для создания проекта с использованием библиотеки Angular, официальный сайт предлагает нам установить пакет angular-cli и далее из консоли запустить определенные команды, которые скачают нужные пакеты, создадут нужные файлы и останется только запустить приложение, однако что если мы не хотим использовать коробочное решение, мы хотим сами создать структуру папок, заполнить ее файлами, подключить нужные библиотеки и собрать, в общем полностью контролировать процесс создания приложения. Я задался таким вопросом, и, после изучения этого вопроса я собрал это в туториал.

Take advantage of JavaScript’s power to build robust web-scale or enterprise applications that are easy to extend and maintain. By applying the design patterns outlined in this practical book, experienced JavaScript developers will learn how to write flexible and resilient code that’s easier—yes, easier—to work with as your code base grows. JavaScript may be the most essential web programming language, but in the real world, JavaScript applications often break when you make changes.

All software design is composition: the act of breaking complex problems down into smaller problems and composing those solutions. Most developers have a limited understanding of compositional techniques. It's time for that to change.

Like other books in this series, You Don’t Know JS: Types & Grammar dives into trickier parts of the language that many JavaScript programmers simply avoid or assume don’t exist (like types).

No matter how much experience you have with JavaScript, odds are you don't fully understand the language. As part of the "You Don't Know JS" series, this compact guide focuses on new features available in ECMAScript 6 (ES6), the latest version of the standard upon which JavaScript is built. Like other books in this series, You Don't Know JS: ES6 & Beyond dives into trickier parts of the language that many JavaScript programmers either avoid or know nothing about.

No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. As part of the "You Don’t Know JS" series, this concise yet in-depth guide focuses on new asynchronous features and performance techniques — including Promises, generators, and Web Workers — that let you create sophisticated single-page web applications and escape callback hell in the process. Like other books in this series, You Don’t Know JS: Async & Performance dives into trickier parts of the language that many JavaScript programmers simply avoid.

No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. This concise, in-depth guide takes you inside JavaScript’s this structure and object prototypes. You’ll learn how they work and why they’re integral to behavior delegation — a design pattern in which objects are linked, rather than cloned.

No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. This concise yet in-depth guide takes you inside scope and closures, two core concepts you need to know to become a more efficient and effective JavaScript programmer.

Get Programming with JavaScript is a hands-on introduction to programming for readers who have never programmed. You'll be writing your own web apps, games, and programs in no time! Foreword by Remy Sharp. About the Book Are you ready to start writing your own web apps, games, and programs? You’re in the right place! Get Programming with JavaScript is a hands-on introduction to programming for readers who have never written a line of code.

The fate of most applications is often sealed before a single line of code has been written. How is that possible? Simply, bad design assures bad results. Good design and effective processes are the foundation on which maintainable applications are built, scaled, and improved.

In order to truly master JavaScript, you need to learn how to work effectively with the language’s flexible, expressive features and how to avoid its pitfalls. No matter how long you’ve been writing JavaScript code, Effective JavaScript will help deepen your understanding of this powerful language, so you can build more predictable, reliable, and maintainable programs. Author David Herman, with his years of experience on Ecma’s JavaScript standardization committee, illuminates the language’s inner workings as never before—helping you take full advantage of JavaScript’s expressiveness.

Разработчики серверных, клиентских или настольных приложений на JavaScript нередко сталкиваются с проблемами, связанными с объектами, функциями, наследованием и другими особенностями этого языка. Какие же приемы разработки приложений на JavaScript являются наиболее удачными? Данная книга дает ответ на этот вопрос, предлагая большое количество различных шаблонов программирования на JavaScript, таких как единственный объект (singleton), фабрика (factory), декоратор (decorator) и другие. Можно сказать, что они являются не только методами решения наиболее типичных задач разработки ПО, но и заготовками решений для целых категорий таких задач.

JavaScript developers commonly rely on collections of reusable JavaScript code–written by themselves or by someone else at their company. Alternatively, they rely on code from a third party. But in all these cases they need to know how to either construct a cross-browser library from scratch or be adept at using and maintaining their library of choice.

This is a book about instructing computers. Computers are about as common as screwdrivers today, but they are quite a bit more complex, and making them do what you want them to do isn’t always easy. If the task you have for your computer is a common, well-understood one, such as showing you your email or acting like a calculator, you can open the appropriate application and get to work.

Like it or not, JavaScript is everywhere these days—from browser to server to mobile—and now you, too, need to learn the language or dive deeper than you have. This concise book guides you into and through JavaScript, written by a veteran programmer who once found himself in the same position. Speaking JavaScript helps you approach the language with four standalone sections.

If you’re like most developers, you rely heavily on JavaScript to build interactive and quick-responding web applications. The problem is that all of those lines of JavaScript code can slow down your apps. This book reveals techniques and strategies to help you eliminate performance bottlenecks during development.

Эта книга поможет вам освоить всю мощь языка программирования JavaScript и научит применять его максимально эффективно.
