Wanna speed up your TypeScript builds and improve your IDE's TypeScript language server performance?

Replace type intersections with interfaces.

Here's how:
1. Search for this: & {
2. Replace the type intersections with an interface.

To be clear, Type vs Interface normally doesn't matter. This is just an edge case where it does.

In fact, I typically prefer types over interfaces.

I typically only use an interface if I need to extend.
