Summary
JavaScript Closures
are crucial for creating
Data Privacy
and
Efficient State Management
within functions, as they allow functions to retain access to their
Original scope
even when
Executed outside
of it. This is achieved by keeping references to the
Outer lexical environment
, thereby maintaining the function's access to its
Scope Chain
even after it has been returned or
Passed around
.
