Summary
In this chapter, we introduced the basic concepts about data binding and the terminology used to indicate the various actors involved in the binding relationship. Then, we started exploring different ways to implement data binding in JavaScript. The simplest way was the manual implementation, which is the manual assignment of values from an object to another after an event generated by the user. We saw that a better implementation should monitor changes on the data source object and update in real time the data target object. We also tried to redefine the properties of an object in order to catch changes and synchronize the data target property, but found that this technique may have some issues.
Our exploration continued with the presentation of the observer pattern and the publisher/subscriber pattern. We used the latter to implement a solution based on observables. Finally, we introduced ECMAScript 6 proxies and described an approach based on them.
In the next chapter, we will...
