From 5332b04f35e60ddb2567b2288efd561e25a2a23b Mon Sep 17 00:00:00 2001 From: Martin Probst Date: Fri, 27 Sep 2019 16:16:10 +0200 Subject: [PATCH] build: TypeScript 3.6 compatibility. (#32908) This PR updates Angular to compile with TypeScript 3.6 while retaining compatibility with TS3.5. We achieve this by inserting several `as any` casts for compatiblity around `ts.CompilerHost` APIs.
