I swore I'd never use AngularJS, rather I would convince my Product Manager (if required then client) also to use React or Vue instead. Still got a high budget project for maintanence and switched back to Angular 1.4. Also I have sweared that never ever will use any FTP client (especially FileZilla) but this project was not maintaining any repository previously and had no SSH supported hosting. I had to use FileZilla to clone the working codebase of the project into local. :(
