"Functions and Variable Scope" Please respond to the following:
Functions are used to organize code when programming. All programming languages, including JavaScript have built-in functions that come as part of the language itself.
Differentiate between the built-in functions and the user defined functions (functions created by the programmer).
Determine whether or not a built-in function can call a function created by the programmer and vice-versa. Provide one (1) example to support your response.
Given the various types of loops available in JavaScript, recommend the one (1) that you believe is better for processing data from an array. Provide a rationale for your response.
