However, the compiler automatically transforms the code so that the list will "silently" receive objects, while the source code only mentions primitive values. For example, the programmer can now write list. add (3) and think as if the int 3 were added to the list; but, the compiler will have actually transformed the line into list. add (new ...
The code generated by RJS was usually loaded using Ajax, e.g. by using Ajax-enabled helper methods Ruby on Rails provides, such as the link_to_remote helper. It was replaced by jQuery as of Rails 3.1 [8] Many of the Ruby on Rails Ajax-enabled helper methods used to work by using Prototype to perform an Ajax request in older versions of Rails.
Basically, object code for the language's interpreter needs to be linked into the executable. Source code fragments for the embedded language can then be passed to an evaluation function as strings. Application control languages can be implemented this way, if the source code is input by the user. Languages with small interpreters are preferred.

In other scenarios, tightly coupled objects can be a better option because the compiler is able to detect errors at compile time and optimize the code at the CPU instruction level. Define Subject and Observer objects. When a subject changes state, all registered observers are notified and updated automatically (and probably asynchronously).
A built-in function, or builtin function, or intrinsic function, is a function for which the compiler generates code at compile time or provides in a way other than for other functions. [23] A built-in function does not need to be defined like other functions since it is built in to the programming language. [24]
If the programmer does not supply a constructor for an instantiable class, Java compiler inserts a default constructor into your code on your behalf. This constructor is known as default constructor. You would not find it in your source code (the java file) as it would be inserted into the code during compilation and exists in .class file.
