So, i started working at as a front end developer at my current job about 3 months ago, my boss now wants me to rebuild the system that took the last developer 5 years to build, and is made up of 40000 loc, in 5 weeks. And because the company cant afford to pay me any more to work full time on it, he's offered me shares instead.

Started a new job this week, picking up the front end development of a property management system, since they're old developer just left.

Oh my god was his code bad, inconsistent use of js versions e.g only sometimes using lambda for anonymous functions, variable names that were a single letter, no comments, no documentation, and over 30000 lines split into almost 30 js files, following the logic of it is as fun as a hedge maze with no exit.
