--description--

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:

const str = "Hello World";
const bySpace = str.split(" ");

const otherString = "How9are7you2today";
const byDigits = otherString.split(/\d/);

bySpace would have the value ["Hello", "World"] and byDigits would have the value ["How", "are", "you", "today"].

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

--instructions--

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.

--hints--

Your code should use the split method.

assert(__helpers.removeJSComments(code).match(/\.split/g));

splitify("Hello World,I-am code") should return ["Hello", "World", "I", "am", "code"].

assert(
  JSON.stringify(splitify('Hello World,I-am code')) ===
    JSON.stringify(['Hello', 'World', 'I', 'am', 'code'])
);

splitify("Earth-is-our home") should return ["Earth", "is", "our", "home"].

assert(
  JSON.stringify(splitify('Earth-is-our home')) ===
    JSON.stringify(['Earth', 'is', 'our', 'home'])
);

splitify("This.is.a-sentence") should return ["This", "is", "a", "sentence"].

assert(
  JSON.stringify(splitify('This.is.a-sentence')) ===
    JSON.stringify(['This', 'is', 'a', 'sentence'])
);
