Refactor: Remove createIsolatedProgram call from getProgramAndAST #5856
Description
Overview
typescript-eslint/packages/typescript-estree/src/parser.ts
Lines 90 to 91 in 09c04fb
That last || createIsolatedProgram(code, extra) should never be hit. We believe it was a just-in-case fallback added long ago that is no longer (and maybe never was) needed.
Removing that case may make #5855 easier.
Marking as accepting PRs with the caveat that everything still has to work as expected. Which may or may not be doable. Good luck! 😄
This issue is from a pairing I had with @bradzacher going over the parser internals.
