Regarding the spread and rest operator, why does it have two names when it does the same thing in both cases? It does spread the values in both cases, right ?

I guess it depends on point of view.

When you declare function it is "rest": function funcName(a, b, ...rest) { console.log(rest); }

When you call function (or fill array, object) and try to pass a few arguments it is "spread":

funcName(...spread); [...spread]; {...spread};
