In the previous blogpost we discussed a way to reduce the amount of global variables by using namespaces. Today, we will be looking into a different way to hide functions and variables. If you write JavaScript code on a regular basis (without being an expert) you might have heard about ‘closures’. While closures are becoming increasingly popular […]

Last post we noticed that variables can easily be attached to the global scope. This isn’t a good thing. The more variables are linked to the global scope the more chance you have creating conflicts. A great way to reduce the impact of your code on the global object is to define namespaces. We do this […]

On March 27, 2014, the Spring community was happy to announce the Spring Framework 4.0.3. The reason why is that it was the first release of the Spring Framework with Java 8 support. Since then, the Spring team worked very hard to provide major updates for the Spring Framework to be even more supportive towards Java 8. […]

JavaScript uses the var-statement to declare variables and bind them to a scope. But this statement isn’t mandatory. In JavaScript you are allowed to define a value without this statement. When you do not use the var-statement, the variable will be added to the Global Object (see previous post). Whenever we execute f we won’t […]

Export To export, follow these steps: Open the connection to the schema where you’re application is located and search for the “Application Express” directory: Right click on the application you want to export and choose “Quick DDL” > […]

Now that we know how to create scopes and how to bind variables to them, we should also be aware of JavaScript’s global object. Whenever we declare a variable with the var-statement, the variable will be bound to the nearest scope. But what happens when there is no scope? It needs to be attached to […]

In our previous post we discussed the importance of functions and scopes. The var-statement is narrowly linked to these concepts. Most Object-Oriented languages are statically typed. This means that you will need to declare the type of the variable you want to define before compiling. JavaScript however is dynamically typed and every value is defined […]
