##Task 1 Create a function that takes an id or DOM element and an array of contents

• If an id is provided, select the element
• Add divs to the element
  • Each div's content must be one of the items from the contents array
• The function must remove all previous content from the DOM element provided
• Throws if:
  • The provided first parameter is neither string or existing DOM element
  • The provided id does not select anything (there is no element that has such an id)
  • Any of the function params is missing
  • Any of the function params is not as described
  • Any of the contents is neither string nor number
    • In that case, the content of the element must not be changed
