Namespace: A namespace is a container that holds a set of identifiers (variables, functions, classes) to prevent naming conflicts between different parts of a program. It helps organize and group related entities together.

Module Scope: Module scope refers to the visibility and accessibility of variables within a module or file. Variables declared at this level can be accessed by other modules if explicitly exported but remain hidden from other parts of the program by default.
