Course Introduction:A closure is a function defined within a nested function that can access variables in the scope of the nested function, including variables after the return value has been returned. They are used to create flexible and reusable code, such as generating terms of the Fibonacci sequence: Define a closure function that generates Fibonacci terms. The closure function captures two variables to store the first two terms of the Fibonacci sequence. Call the closure function to calculate and return the new Fibonacci terms in turn. Closure functions can change the value of a captured variable over time, thereby generating subsequent terms in the Fibonacci sequence.
