can you tell the use of a namespace in Web Development?

• A namespace is a declarative area that gives the names of the types, functions, variables, etc. inside of it a scope. Code is arranged logically into namespaces to avoid name collisions, which can happen notably when your code base contains several libraries

A namespace is a logical grouping of names used in a programme that serves as the context for identifiers. A unique identifier must identify an entity within the same context and scope.A directory in an operating system is a namespace. Although every file and subdirectory has a distinct name, a single file may reuse that name more than once.
