--description--

Create a getTotalIngredients function that takes a single argument, representing an array with ingredients, and returns the number of ingredients from the array passed to the function.

--hints--

You should create a getTotalIngredients function.

js
assert.isFunction(getTotalIngredients);

Your getTotalIngredients function should have a single parameter.

js
assert.lengthOf(getTotalIngredients, 1);

Your getTotalIngredients function should return a number.

js
assert.isNumber(getTotalIngredients(recipe1.ingredients));

getTotalIngredients(recipe1.ingredients) should return 4.

js
assert.strictEqual(getTotalIngredients(recipe1.ingredients), 4);

getTotalIngredients(recipe2.ingredients) should return 5.

js
assert.strictEqual(getTotalIngredients(recipe2.ingredients), 5);

getTotalIngredients(recipe3.ingredients) should return 3.

js
assert.strictEqual(getTotalIngredients(recipe3.ingredients), 3);
