javascript - Why are jQuery objects inherently unique? -


reading jquery objects here, states jquery objects unique, if "this true if object created same selector or contain references exact same dom elements."

so example, following equate false:

$( "#logo" ) === $( "#logo" )

why jquery objects unique?

thanks

because, essentially, jquery using factory pattern creates new instance of jquery object selector each time call it.

as these different instances, not equal.
