This is the philosophy behindtemplate inheritance. Be decoupled from HTML¶ The template system shouldn’t be designed so that it only outputs HTML. It should be equally good at generating other text-based formats, or just plain text.

• Object-oriented programming allows re-usability of code. That is, the objects created in one program can be re-used in other programs. In addition, new classes can be created with the help of existing ones using inheritance. It leads to faster software development and high-quality program...
5. Object-Oriented JS and Prototypal Inheritance i. Function Constructors When you call a function with the new keyword, a new object is created in memory, and is made available to the function via the this keyword. Functions designed to be called like that are called constructors. var My...
