object-no-new-keys
Check, does a plain object (AST/JSON) has any unique keys, not present in a reference object (another AST/JSON)
Install
The latest version is ESM only: Node 12+ is needed to use it and it must be import
ed instead of require
d. If your project is not on ESM yet and you want to use require
, use an older version of this program, 3.1.0
.
npm i object-no-new-keys
