jQuery what is the difference between $('') and $('p')

Question

Can someone explain to me the difference between $(\'

\') and $(\'p\') in jQuery.

for example, if i write:

$(\'body\').         


        

Answer 1

$('

') creates a new paragraph (

) element. (

)

$('p') selects all existing paragraph elements.

For example:

$('p').after($('
').html('foo'))

Will select all paragraphs and add new paragraphs after them.
