JavaScript: Moving to ES2015

Chapter 5. JavaScript Patterns

So far, we have looked at several fundamental building blocks necessary to write code in JavaScript. Once you start building larger systems using these fundamental constructs, you soon realize that there can be a standard way of doing a few things. While developing a large system, you will encounter repetitive problems; a pattern intends to provide a standardized solution to such known and identified problems. A pattern can be seen as a best practice, useful abstraction, or template to solve common problems. Writing maintainable code is difficult. The key to write modular, correct, and maintainable code is the ability to understand the repeating themes and use common templates to write optimized solutions to these. ...
