‘#someDiv’ is a CSS3CSS selector which is semantically equivalent to getElementById('someDiv'), in that it will select the element with ID ‘someDiv’. So:

document.getElementById('someDiv')

==

// bracket notation will return a DOM element
$("#someDiv")[0]

// leaving it out will return a jQuery object
$("#someDiv")
