How do dom structure operations add, remove, move, copy, create, and find nodes? (Must Meet)
1. Create a new node
createDocumentFragment( ) // Creates a DOM fragment
createElement( ) // Creates a concrete element
createTextnode( ) // Creates a text node
2. Add, remove, replace, insert
appendChild( )
removeChild( )
replaceChild( )
insertBefore( ) // and no insertAfter()
3. Find
getElementsByTagName( ) // by tag name
getElementsByName( ) // Via the value of the element's Name attribute (IE is more fault tolerant and results in an array that includes an id equal to the name value)
getElementById( ) // Uniqueness through element Id
