let a = "1";
let b = "2";
let obj = {a, b};//{a:"1", b:"2"} when initializing an object, pass in {a, b} directly, and the resulting object will have two properties, the key and value of which are the variable name and value of ab, respectively.
what is the name of sugar in this grammar?
you can call him attribute abbreviation
this really does not have a clear Chinese name. The attribute abbreviation mentioned by hfhan is the closest, which is called Shorthand property (ES2015 introduction, that is, ES6).
Why is it called shorthand?
because {a, b} is equivalent to the abbreviation of {a: a, b: B}
because it should be called deconstruction assignment
I also think it should be called structural assignment . Please take a look at teacher Ruan Yifeng's article
deconstruction assignment, most people should say so.

A solution that conforms to the meaning of the question function unique(arr) { const res = new Map(); return arr.filter((a) => !res.has(a) && res.set(a, 1)) } because map key is unique, you can change the an in res.has (a) to whate...
