Issues compiling CDK projects ("TS2300: Duplicate identifier 'IteratorResult'") #3839
Description
Applications created using the current "init templates" for TypeScript may fail building with the following error message:
node_modules/@types/node/index.d.ts:97:11 - error TS2300: Duplicate identifier 'IteratorResult'.
97 interface IteratorResult<T> { }
~~~~~~~~~~~~~~
node_modules/typescript/lib/lib.es2015.iterable.d.ts:41:6
41 type IteratorResult<T, TReturn = any> = IteratorYieldResult<T> | IteratorReturnResult<TReturn>;
~~~~~~~~~~~~~~
'IteratorResult' was also declared here.

This can be fixed by removing the @types/node dependency declared in package.json, or upgrading it from 8.10.45 to 8.10.52, by running the following command:
$ npm install @types/node@8
+ @types/node@8.10.52
