Description
What is changing?
Typescript will now be able to narrow the types of symbol properties! So a lot of nullish checks came up.
Typescript now has more strictness about constrained generics, we need to make sure the whole chain of generics we pipe through is constrained, basically
extends Document
everywhere.The CI will fail, 4.6 still can't narrow symbol types so I want to check with the team before I go and write the "pull out to a normal variable" code everywhere.
What is the motivation for this change?
Types in our script made with java ☕ .
Also covers: NODE-4123, NODE-4117
Double check the following
npm run check:lint
