The current TypeScript "with-typescript" looks like it was put there as a place holder. I'm fairly new to TypeScript but I'm sure the changes I've made here will be a huge improvement. Open to suggestions and to update as appropriate. Also, Tried to run yarn lint --fix to no avail. I can't figure out how to get it to find lint whether I'm running on my mac or PC. I tried lots of variations around npm i lint -g but had no success. (#6011)
