91Using Functions For Out of Scope Code

There are times when code is written as one long monolithic process, or when there are enough conditional and loop statements being indented where understanding what is happening in a particular code block gets hard to keep track of. Oftentimes, this means that the code’s intent, or scope, has gone a step too far from the original intent. In these cases, code blocks which serve a particular purpose should be placed into their own named function to make readability easier. As in the previous newBar() function example, the context for that purpose can be provided by the function’s name and the arguments passed into it.
