When to use $(this).text() and when to use $.text([this])

Question

A previous stackoverflow question had this as part of its solution:

$.text([this])

I've never seen that syntax before. The complete statement was:

return $.text([this]).indexOf(myInput) == 0

So I'm thinking $(this).text() couldn't be used.

Q: Where is $.text([this]) mentioned in any of the documentation?

Answer 1

It's just more efficient to use $.text([this]) when you don't need the jQuery object created by $(this). They do the same thing, just no need to create the jQuery object along the way.

It's not AFAIK, you're calling jQuery.text which (in the current version) is just an alias for Sizzle.getText.
