[Typescript] Step1 & 2 for converting a js app to ts
作者：互联网
1. Compiling in "loose mode"
- Start with all tests passing
- Rename all .js to .ts, allowing implicit any
- Fix only things that are not type-checking, or causing compile errors
- Be careful to avoid changing behavior of function
- Get test passing again.
# rename all JSX files in src/ to TSX
find src -name '*.jsx' -exec bash -c 'git mv "$0" "${0%.jsx}.tsx"' "{}" \;
# rename all JS files in src/ to TS
find src -name '*.js' -exec bash -c 'git mv "$0" "${0%.js}.ts"' "{}" \;
# rename all JSX files in src/ to TSX
find tests -name '*.jsx' -exec bash -c 'git mv "$0" "${0%.jsx}.tsx"' "{}" \;
# rename all JSX files in src/ to TSX
find tests -name '*.jsx.snap' -exec bash -c 'git mv "$0" "${0%.jsx.snap}.tsx.snap"' "{}" \;
# rename all JS files in tests/ to TS
find tests -name '*.js' -exec bash -c 'git mv "$0" "${0%.js}.ts"' "{}" \;index.html

```2. Explicit Any
- Start with tests passing
- Ban implicit any
"noImplicityAny": true,
- Where possible, provide a specific and appropriate type
- Import types for dependencies from DefinitelyTypes
- otherwise explicit any
- Get tests passing again
