Prepend the debugger statement to a function as easy as stopBefore('Element.prototype.removeChild'). Works in Chrome DevTools and Safari Inspector, doesn’t work in Firebug‘s and Firefox Developer Tools‘ console (I don’t know why). Works as a standalone script everywhere.

Examples

stopBefore(document, 'getElementById')
stopBefore('document.getElementById') // the same as the previous
stopBefore(Element.prototype, 'removeChild')

Have on.js do it for you!

L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns
