Description

Apparently pull requests do not suffice and enhancement requests need their own bug ticket, so here goes.

I’ve made this pull request on GitHub: https://github.com/jquery/jquery/pull/205

The changes I made are some minor optimizations to globalEval, namely:

  • Use the speedy document.head when it’s available in globalEval.
  • Don’t set script.type = text/javascript as it’s not needed — all browsers default to text/javascript if the type attribute is omitted (and it’s valid HTML too).

Bullet 1 is a no-brainer, but I'd like to see a 

 document.head || document.getElementsByTagName( "head" )[ 0 ] || document.documentElement
reference cached, because this is used elsewhere as well.

I definitely agree with bullet 2, without question. As far as I'm concerned setting the type is a waste of characters.

Fixes #8098. Use the fast document.head when available. Don't set unneeded "script.type = text/javascript".
