--description--

Spinal case is a string format where all words are in lowercase and separated by hyphens. "this-is-spinal-tap" is an example of a string in spinal case.

In this lab, you will create a function that converts a given string to spinal case.

Objective: Fulfill the user stories below and get all the tests to pass to complete the lab.

User Stories:

1. You should create a function named spinalCase.
2. The spinalCase function should take a single argument, a string.
3. The spinalCase function should return the string in spinal case format. For example, if the argument is ProductLanding page, the function should return product-landing-page.

--hints--

You should create a function named spinalCase.

assert.isFunction(spinalCase);

spinalCase should take a single argument.

assert.lengthOf(spinalCase, 1);

spinalCase("This Is Spinal Tap") should return the string this-is-spinal-tap.

assert.deepEqual(spinalCase('This Is Spinal Tap'), 'this-is-spinal-tap');

spinalCase("thisIsSpinalTap") should return the string this-is-spinal-tap.

assert.strictEqual(spinalCase('thisIsSpinalTap'), 'this-is-spinal-tap');

spinalCase("The_Andy_Griffith_Show") should return the string the-andy-griffith-show.

assert.strictEqual(
  spinalCase('The_Andy_Griffith_Show'),
  'the-andy-griffith-show'
);

spinalCase("Teletubbies say Eh-oh") should return the string teletubbies-say-eh-oh.

assert.strictEqual(
  spinalCase('Teletubbies say Eh-oh'),
  'teletubbies-say-eh-oh'
);

spinalCase("AllThe-small Things") should return the string all-the-small-things.

assert.strictEqual(spinalCase('AllThe-small Things'), 'all-the-small-things');

function spinalCase(str) {
