I'm translating some Clojure code to Javascript for my job for transparency for the UI team and I realized why I prefer Clojure for Javascript. Here's the problem:

Select only unique objects from a list

Javascript:

const myDistinctArray = [
  ...new Set(myObjArray.map(JSON.stringify)),
].map(JSON.parse);

or

// This one presumes unique "id" === unique object 
let uniqueObjArray = [
  ...new Map(
    objArray.map((item) => [item["id"], item])
  ).values(),
];

Clojure

(distinct my-object-list) // that's it

Why does the Clojure one work?

Clojure promotes immutability by default, and this includes maps. So maps are compared directly by value and not by reference or identity.

Conclusion

The beautiful thing about Clojure is how expressive the language is and how much you can say with very few lines of code.
