/**
|
||
|
|
Create a type from an object type without certain keys.
|
||
|
|
|
||
|
|
This type is a stricter version of [`Omit`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-5.html#the-omit-helper-type). The `Omit` type does not restrict the omitted keys to be keys present on the given type, while `Except` does. The benefits of a stricter type are avoiding typos and allowing the compiler to pick up on rename refactors automatically.

Please upvote [this issue](https://github.com/microsoft/TypeScript/issues/30825) if you want to have the stricter version as a built-in in TypeScript.
