I am working on a WebGL project with Javascript and I'm finding it really difficult to trace an error in my code.

In order to debug the program, I'm in need of a watchpoint checker, so that I can check when does the faulty variable data getting changed.

Currently I am using Chrome browser, which lacks this feature in development tool. Can someone suggest me some advanced developer toolkit for Javascript debugging that has got watchpoint feature?

Check this

Instead of writing again and again a variable name or an expression you are going to check a lot during a debug session, add it to the ‘Watch Expression’ list. You refresh the values if you modify them directly, or just watch them change while the code runs

If you are using Chrome, you can try the experimental Object.observe():
