Everyone is talking about Ivy for Angular compilation. All I have heard is good things about it. Are there any downsides? like something I should be aware of before using it?
Bundle sizes may be larger than without Ivy and strict template type checking may give you some problems.
Those issues should be resolved in 9.0.0 final. The RC is coming soon and is worth testing out.
