The New Dragons in JavaScript

Explore the nuances and potential pitfalls of ECMAScript 2015 features in this 54-minute conference talk from NDC Conferences. Delve into the complexities of string templates, arrow functions, promises, and modules, examining their impact on code maintainability and application performance. Learn how to effectively use these features while avoiding common mistakes that can confuse developers or degrade runtime efficiency. Gain insights on topics such as arrow syntax, lexical 'this' references, destructuring, classes, hoisting, exports, and immutable bindings. Discover the challenges faced by library and framework authors when implementing these features, and understand how tools like WebPack can address potential issues in modern JavaScript development.
