how to find where the variable is modified

Question

I have a variable join in a page whose value is either true or false.

When I run the page, how can I know which method modified the variable using the debug tool in chrome?

what do you mean which method , please be more specific , provide a code or fiddle. — ProllyGeek, Nov 03 '14 at 03:15
you can use a getter/setter and log arguments.callee.caller in the setter — dandavis, Nov 03 '14 at 03:17
or just set a breakpoint or watch in the devtools sources pane — dandavis, Nov 03 '14 at 03:18

Use the debugger keyword in your code. This is the equivalent of setting a breakpoint in a debugger. When the browser hits the debugger the program will stop and you can inspect the stack trace from the dev tools.

Read this on debugging javascript.
