Let's learn how to speed up our Angular Jest tests by more than 100% by switching to Jest ESM (a notoriously problematic migration) and how to solve all the troublesome issues that tend to pop up along the way!

From angular 16, ngcc was removed. Should we still using jest-preset-angular or there is a better way?

I am using angular version 16, which by default have under @angular/cdk only fesm2022. Should down-leveling to fesm2015 would work out of the box If there is no fesm2015 under my @angular/cdk directory?

Would highly appreciate an update to this blog, relevant to Angular 18 and Nx.
All my attempts to fix the dreaded message SyntaxError: Cannot use import statement outside a module have failed. I'm totally confused....
I'm using Angular 18 inside an Nx monorepo.
