// *** Functional Programming: Split a String into an Array Using the split Method ***

// The split method splits a string into an array of strings. It takes an argument
// for the delimiter, which can be a character to use to break up the string or a
// regular expression. For example, if the delimiter is a space, you get an array 
// of words, and if the delimiter is an empty string, you get an array of each 
// character in the string.

// Here are two examples that split one string by spaces, then another by digits
//  using a regular expression:

//     var str = "Hello World";
//     var bySpace = str.split(" ");
//     Sets bySpace to ["Hello", "World"]

//     var otherString = "How9are7you2today";
//     var byDigits = otherString.split(/\d/);
//     Sets byDigits to ["How", "are", "you", "today"]

// Since strings are immutable, the split method makes it easier to work with them.


// # Use the split method inside the splitify function to split str into an array
//   of words. The function should return the array. Note that the words are not 
//   always separated by spaces, and the array should not contain punctuation.


function splitify(str) {
  // Add your code below this line
  
  // replace(/[\. , -]+/g, " ") is a regexp that replaces every '.', ',' or '-' with an empty space
  const regex
  return str.replace(/[\. , -]+/g, " ").split(' ');

  // Add your code above this line
}
splitify("Hello World,I-am code");
