You can put a

debugger;

to break in most of the JavaScript environments. They will persist for sure. It's good to have a minifier that rids the debugger and console.log calls for the production environment, if you are using these.

In the recent versions of Chrome browser, there is a "Preserve Log" option on the top of the console panel, next to the filters. In the older versions, right clicking on the empty console window will bring that option ("Preserve log upon navigation"). It's handy when you don't have console.log statements or hard-coded debugger calls.

update: I found a tool on github, called chimney, which takes a file and removes all the console.log calls. it gives a good idea about how to remove debugger calls.
