The third beta of the next generation ArcGIS API for JavaScript is now available. This is the last planned beta before the actual 4.0 release.


Version 4.0 beta 3 of the ArcGIS API for JavaScript has been released. Read about it in the blog at or check out the details in the Whats New.


This includes a new model for widgets where code and presentation is separated to make it easier to enhance and customize the widgets. There will be some further fine-tuning of this in the non-beta 4.0 release. But already now, it should be easier to use the widgets when working with other frameworks and libraries such as Bootstrap, React, and JQuery.


It also includes updates to the renderer classes to extend the Accessor class. This is part of the general update to 4.x for a consistent way of Working with properties | ArcGIS API for JavaScript .


As part of this beta release, the placeholder syntax when using template strings have changed. Instead of ${placeholder}, you just drop the dollar sign and use {placeholder}. This allows the API to avoid conflict with ES6 template strings.
