I think this all looks good to me, I built the compiler and used it to compile the ionic framework without issues, and the upgrade itself looks straightforward enough so it's a 👍 from me
Also worth calling out I did TAL at https://github.com/microsoft/TypeScript/wiki/API-Breaking-Changes#typescript-47 for v4.7, v4.6, and verified we aren't using any of the APIs that broke (there was just one) |

I was getting an error message because we recently upgraded typescript (#3530) saying that 4.7 wasn't supported by the installed versions of @typescript-eslint/parser and @typescript-eslint/eslint-plugin. This just bumps them a little bit to fix that error message.

What is the new behavior?
this pr adds support through v4.7.4 of typescript in 2 commits:
increment support through TypeScript v4.6
to add support for TypeScript 4.6, the

,but does in

increment support through TypeScript v4.7
in v4.7 of TypeScript,

gained theEventCount

Does this introduce a breaking change?
