Discussion on: Code Snippet Series: Get Unique Values from Array

[Functional Javascript]

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 } }
