how web browser know if script inside <script> tag has finished loading?

the onload event fires when resource (such script, or stylesheet) loaded:

var oscript = document.createelement("script"); oscript.type = "text\/javascript"; oscript.onload = function () {   // when script loaded } document.getelementsbytagname("head")[0].appendchild(oscript); oscript.src = "path/to/script";

the onload event not work on inline scripts.
