Question

Can someone please explain me this code?

let [learn,solo="solo"] = "learn";
[solo, learn] = [learn, solo];
console.log(solo + learn); //le

I think it has to do with ES6 and I don't fully understand this lesson.

Answer 2

sorry my mistake... should be

let [learn,solo="solo"] = "learn"; // learn = "l", solo = "e"

[solo, learn] = [learn, solo]; // solo = "l", learn = "e" (exchange)

console.log(solo + learn); // solo + learn = "le"

Answer 3

Nguyễn Văn Hoàng thanks.

Answer 4

Calviղ I also thought the output would be "learnsolo" but when I tested it in the code playground the output was "le". Don't know why though. This was actually a challenge.

Answer 5

let [learn,solo="solo"] = "learn"; // learn = "learn", solo = "solo"

[solo, learn] = [learn, solo]; // solo = "learn", learn = "solo"

console.log(solo + learn); // solo + learn = "learnsolo"
