function getTokens(rawString) {
  // NB: `.filter(Boolean)` removes any falsy items from an array
  return rawString.toLowerCase().split(/[ ,!.";:-]+/).filter(Boolean).sort();
  //converts all the letters in the string to lowercase, splits the string into an array of individual words, removes any falsy items, and sorts it all alphabetically.
}

function mostFrequentWord(text) {
  let words = getTokens(text);
  //calls the function getTokens and assigns the output to words
  //makes words an array of the individual words from the argument, sorted alphabetically, in lowercase and without punctuation or spaces

Scope is where a variable can be accessed from in your program. Block scope means that the variable can only be accessed from within the block where it is declared. Whereas variables with global scope can be accessed from anywhere in the program.

Global variables are usually avoided due to the unintended side effects that can happen, which can often lead to bugs. Side effects are when a variable in a function reaches out of the local scope and changes the value of the global variable.
This can cause a function to become indeterminate, which means that it returns different values despite having the same inputs. A pure function is determinate, always returning the same values for the sames inputs, and has no side effects, so only changes variables within the local scope.
Strict mode triggers an error whenever a function is declared without let or const. It prevents you from accidentally declaring a global variable within a function.
