+What is ASCII and how does it work with `charCodeAt()` and `fromCharCode()`?
 
 In programming, understanding how characters are represented as numbers is fundamental. This is where ASCII comes in. ASCII, short for American Standard Code for Information Interchange, is a character encoding standard used in computers to represent text. It assigns a numeric value to each character, which is universally recognized by machines.

 A function call, or or invocation, is when we actually use or execute the function. To call a function, you will need to reference the function name followed by a set of parentheses:

 To create a new array where each number is doubled, we are using the `map` method. The `map` method accepts a callback function where the function is called on every single element in the array.

 If you need to sort numbers, then you will need to pass in a compare function. The `sort` method converts the elements to strings and then compares their sequences of UTF-16 code units values. UTF-16 code units are the numeric values that represent the characters in the string. Examples of UTF-16 code units are the numbers 65, 66, and 67 which represent the characters "A", "B", and "C" respectively. So the number 200 appears before the number 3 in an array, because the string "200" comes before the string "3" when comparing their UTF-16 code units.
