Nested functions are defined inside of other functions. A nested function can see (access) all local objects (data, functions, types, etc.)
A nested function, also known as a nested procedure or subroutine, is a function that is declared inside of another function known as the enclosing function in computer programming. A nested function can see (access) all local objects (data, functions, types, etc.) of both its immediately enclosing function and any function(s) that, in turn, enclose that function, but is itself invisible outside of its immediately enclosing function due to basic recursive scope rules. Although only a few levels are often utilized in actual systems, layering is theoretically conceivable to an infinite depth. Many early approaches to structured programming, including ALGOL, Simulate 67, and Pascal, as well as many contemporary dynamic languages and functional languages, use nested functions.

The code above is a function called "search" that takes in two parameters, an array of integers called "arr" and an integer called "target". The function uses a for-each loop to iterate through the elements of the array "arr".
Within the loop, it uses an if statement to check if the current element (referred to as "number") is equal to the target value passed in as a parameter. If the current element is equal to the target value, the code returns "true" indicating that the target value is present in the array. If the loop completes without finding a match, the code will return "false" indicating that the target value is not present in the array.
