well I can, I wrote a year-long js project that I abandoned as refactorings gradually turned into eternal bug-fests. I started from scratch in typescript, and the project is now 3x the dead project, with none of the bugs. and refactorings have become painless, with the compiler tools and editor telling me what I must fix up. There may be a special breed of programmers who need no such help, but I have yet to meet them in my 32+y long professional programming career :-)
