In TypeScript 4.2 the `__spread` and `__spreadArrays` helpers were both replaced by the new helper function `__spreadArray` in microsoft/TypeScript#41523. These helpers may be used in downleveled JavaScript bundles that ngcc has to process, so ngcc has the ability to statically detect these helpers and provide evaluation logic for them. Because Angular is adopting support for TypeScript 4.2 it becomes possible for libraries to be compiled by TypeScript 4.2 and thus ngcc has to add support for the `__spreadArray` helper. The deprecated `__spread` and `__spreadArrays` helpers are not affected by this change. Closes #40394 PR Close #41201 |
