US Urmil K S. Senior Software Engineer Information Technology and Services Enterprise (\> 1000 emp.) 1/5/2016 "Sencha Touch review" 1.5/5 What do you like best about Ext JS? Sencha touch is completely driven by javascript and a very comprehensive API docs. I delivered more than 3 projects with varying complexity and found it to be effective. I'm a Mobile application development consultant and used in the Cordova based project. The best part for me considering I'm an Objective-C developer, I just was not interested in dealing with HTML. Review collected by and hosted on G2.com. What do you dislike about Ext JS? The stuff I disliked the most was performance on Android devices. And the fact if I want to include some extension developed for Sencha Touch 1.x in Sencha Touch 2.x it simply won't compile. Review collected by and hosted on G2.com. Recommendations to others considering Ext JS: With Sencha Touch Merging with EXT JS and becoming a licensed software, I will not advise it anymore. Bootstrap, Angular and other frameworks are faster in performance just developer needs to deal with HTML. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? I work in enterprise mobility and mostly working on apps around it. Review collected by and hosted on G2.com.

Nice and tidy declarative syntax, easy to fast prototype applications with it Review collected by and hosted on G2.com. What do you dislike about Ext JS? Difficult to customize, peculiar workflow, knowledge gained on it is not reusable Review collected by and hosted on G2.com. Recommendations to others considering Ext JS: The following recommendations are based on my experience with Sencha Touch 2.4.0. Overall it's a very nice framework, affected by lot of small defects, and undocumented features that just seem to be there to tempt developers to subscribe to the paid support. Sencha's development paradigm is declarative, elegant and tidy, but because it's very peculiar it's hard to reuse the skills gained on it in other contexts. It's easy to build fast prototypes of an application, but can be a headache to implement custom behaviors. Nowadays I would not recommend investing the time to climb Sencha's steep learning curve unless you have previous Ext.js experience, there are other more traditional and easy to learn solutions out there. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? Developed four hybrid mobile applications for Android and iOS.
