High Performance JavaScript Patterns

JavaScript frameworks are great, but you don't need to rely on them to create maintainable, high performance applications. In fact, the more code you can create independent of a framework, the more reuse you'll get from it, regardless of the frameworks being used. Understanding these patterns (and antipatterns!) will help you write maintainable, high performance code for both client and server, regardless of which libraries and frameworks you use.

You will leave this workshop armed with a toolbox for building and profiling JavaScript to run anywhere. We will examine:

• Basic JavaScript patterns.
• Efficient (and non-efficient!) iteration patterns.
• Closures, anonymous functions, immediately-invoked expressions, and scoping.
• Objects, prototypes, modules, and mixins.
• Pubsub patterns.
• The right ways to write and wrangle asynchronous code, including promises and async libraries.
