An Overview of JavaScript Design Patterns . This is a structural design pattern focused on efficient data sharing through fine-grained objects. Flyweight design pattern is very useful in an application which needs same kind of objects in repetition. Flyweight Design Pattern. Flyweight pattern tries to reuse already existing similar kind objects by storing them and creates a new object when no matching object is found. by concreate flyweight. Basically, it creates a Flyweight object which is shared by multiple contexts. A flyweight is an object that minimizes memory use by sharing as much data as possible with other similar objects it is a way to use objects in large numbers when a simple repeated representation would use an unacceptable amount of memory.

When creating many thousands of identical objects, stateless flyweights can lower the memory used to a manageable level. In computer programming, flyweight is a software design pattern. A Flyweight Pattern says that just "to reuse already existing similar kind of objects by storing them and create new object when no matching object is found".. This type of design pattern comes under structural pattern as this pattern provides ways to decrease object count thus improving the object structure of application. There are a couple common examples you’ll find on the Internet and in software engineering books: painting large numbers of character objects in a document editing application (Go4) or rendering large numbers of trees in a landscape on the screen.
