Summary:
Annotations inside of destructuring (e.g. `const [foo: number] = ...`) are invalid Flow syntax. We currently ignore them, and in the future will error on them (D35304565).
Remove them using the codemod from D35390352
Locally changed WWW_ROOT, FLOW_ROOTS, and excluded paths in scripts/typedjs/flow/runner.config.js (e.g. P492224584) - and then
```
scripts/typedjs/flow/runner codemod removeAnnotationsInDestructuring ~/fbsource/xplat/js
```
formatting files didn't work, so do it manually
