Closures
Closures
Introduction
Hello,
Closures are self-contained blocks of code. A closure is passed as a parameter to the code, or it can be used inside codes.
The closure is a type of function. It can be used by passing within the code. They are similar to lambdas in other programming languages.
memory management
One of the most important points is that Closure can store the values of constant and variables in the context it is defined.
This storage is known as closing-over.
Swift does the memory management during this storage for us.
