Electron. 20 Essential Java Interview Questions and Answers. The key difference between is that inner classes have full access to the fields and methods of the enclosing class. This can be convenient for event handlers, but comes at a cost: every instance of an inner class retains and requires a reference to its enclosing class. With this cost in mind, there are many situations where we should prefer static nested classes. When instances of the nested class will outlive instances of the enclosing class, the nested class should be static to prevent memory leaks.
Consider this implementation of the factory pattern: public interface WidgetParser { Widget parse(String str); } public class WidgetParserFactory { public WidgetParserFactory(ParseConfig config) { ... } public WidgetParser create() { new WidgetParserImpl(...); } private class WidgetParserImpl implements WidgetParser { ... At a glance, this design looks good: the WidgetParserFactory hides the implementation details of the parser with the nested class WidgetParserImpl. 25 Essential Questions Asked in Top JavaScript Interviews.

AWS. How to prepare for a Front-end Developer interview? I usually supplement the interview with a take home project, because front end web dev (emphasis on web) is about building interfaces and managing state really well and that is hard to test in an hour! Some of the more domain specific stuff is about building a scalable components library that your team can use, testing your code, building assets in the most elegant way possible (gulp, webpack, grunt). So make sure you're very honest with your resume!! (dishonesty is bad).

Shadow DOM has long been a talking point on the web, and the Polymer project pushes the proof of concept quite nicely, however, adoption of “raw” Web Components (Shadow DOM is part of the spec) is low.
Instead, frameworks have provided “better” ways to achieve results and develop applications. Angular 2 isn’t ignorant to Web Components at all, and provides us the powerful ability to use native Shadow DOM when we choose. We also have the choice to emulate Shadow DOM through Angular 2, achieving somewhat encapsulated Components and styling.
If you need an overview on Web Components and Shadow DOM, I’d check out my article on it! Problem we’re solving The problem in the way we create web applications lies in the “global-like” architecture that HTML, CSS and JavaScript gives us, for instance an .active {} class will be painted to all DOM elements containing the class name active, such as <div class="active"></div>. Style property Global CSS ViewEncapsulation.Emulated Woah! Why use TypeScript instead of just using JavaScript? - Dave Voyles. TLDR:Type safety, productivity, intellisense, and debugging.
In continuing with my recent trend of using TypeScript, I wanted to illustrate how to create functions and variables in TypeScript, because this initially threw me into a loop. The code for this example can be found here. JavaScript and C# are the two languages I use in most of my day-to-day work, so I figured combining the two would be a joy.
