Objects won't work with non-string keys, as well as nasty strings (e.g. __proto__).
__proto__
Correct, these funcs work with the primitives (string and number).
Ref types (comparing objects and arrays) require custom logic, even if working with Set and Map.
eg...
const aDups = [{ id: 1 }, { id: 1 }, { id: 1 }, { id: 1}]; const setDups = new Set(aDups) console.log(setDups) // output: // Set(4) { { id: 1 }, { id: 1 }, { id: 1 }, { id: 1 } }
