Before you actually start learning Angular, you need to understand a few concepts such as: Difference between traditional web-applications and single-page applications AngularJS drawbacks What is Angular? To begin with, let me first tell you what is the difference between traditional web-applications and single-page applications? Traditional Web-apps: I’m sure you will remember that in the past, whenever you would request for a web page, the page used to reload entirely in order to load the data as shown in the image above.

To overcomes this problem,  SPA’s or Single-Page Applications model  was introduced.  SPAs  are browser applications that are similar to mobile applications that come with dynamic interactions. They have much lesser refresh rates when compared to  TWA’s . Take a look at the image below that depicts the SPA model where

What is Java Unit testing, and how do I learn it... Java Unit testing is when you create small tests to verify that small bits of your code are working as “units.” Typically you write these tests in Java itself. In each test, you might get the system into a certain state, then you interact with the system to exercise the behavior you want to test. You finally verify whether or not the system did what you expected. A primary goal is to reduce the number of defects that you integrate into the rest of the source base. You’ll find numerous tutorial articles if you search. Most people use JUnit, a simple tool that you’ll find in Eclipse or IDEA.
