Week 2 Discussion

" 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.
