ojet-vbcs

  My experience of working with  #OracleJET  and  #VBCS . I have worked extensively in both. My personal choice is oracle JET because it provides more flexibility in complex implementation. VBCS is for business users and Oracle JET is for advanced JavaScript developers. Development speed is fast in VBCS compared to OJET because VBCS supports drag and drop visual development. OJET is completely code based development. Hence, VBCS is for small and simple applications and OJET is for complex applications. VBCS is a web builder on top of the OJET library so internally it uses OJET only. OJET has more inbuilt features than available in VBCS. You can extend VBCS to use missing OJET features. Enjoy!

The JavaScript bind(this) method is very confusing  for beginners. But It is being used frequently when we have deep nested context.  The Problem with the code below is that when a promise is fulfilled reference to 'this' will no longer be available. promise.then(function(data) { this.foo(data, "data"); }, function(err) { // error handling }); One of the common solutions is to create a variable 'self' and below code will work. var self = this; promise.then(function(data) { self.foo(data, "data"); }, function(err) { // error handling }); Personally, I don't like the above approach. We can have better and cleaner code using bind() to keep the context of "this". promise.then( function( data ) { this.foo( data, "data" ); }.bind(this), function(err) { this.error(err); }.bind(this) );
