Coordinate Transformation

[alpine crown]

Could you share what you tried, if anything?

wait

export function translate2d(dx, dy) {
function move() {
return [dx + dx, dy + dy];
}
return move;
}

Increase your chance of getting help and look like a pro by sharing codeblocks not images. For example, you can type the following. Note, the ``` must be on their own line.
```
for number in range(10):
total += number;
```
Discord will render that as so:

for number in range(10):
    total += number;

I think move is supposed to accept arguments maybe?

[shadow hamlet]

I'll try

wait

but what args?

[alpine crown]

That's a lot of waiting you're having us do 🙂

The example shows,

const moveCoordinatesRight2Px = translate2d(2, 0);
const result = moveCoordinatesRight2Px(4, 8);
// result => [6, 8]

[shadow hamlet]

what do you mean?

[alpine crown]

You told me to "wait" twice

Node how the translate2d() takes two values and returns a function. That function also takes two values.

[shadow hamlet]

lol yeah.

[alpine crown]

The result is the addition of those two sets.

[shadow hamlet]

makes sense

[alpine crown]

const move = translate2d(2, 0);
const result = move(4, 8);

That's four unique values (variables?)

done with the first taks

task*

[alpine crown]

🎉

[shadow hamlet]

Thank you!

for your time and effort.

[alpine crown]

You're very welcome

In the future, you may want to consider not telling people on the internet to wait 😉

If everything is resolved, we ask that the person who posted the request react to the top/original post with a :white_check_mark: (:white_check_mark:). This indicates to others that this issue has been resolved and locks the thread.
If all the tests pass and you want to further improve your solution, we encourage you to use the "Request a Code Review" feature on the website!

[shadow hamlet]

I shall keep that in mind.

Any other requests good sire?

[alpine crown]

Nope. That's all.

[shadow hamlet]

splendid.

Are you still there?

Stuck again on task 3

I'm not sure If I'm allowed to tag you.

[alpine crown]

Ideally I'm not the only one who can help 😉 And I have other stuff going on from time to time.

Could you share what you tried? What's the error? Please don't use images to share text.

[shadow hamlet]

I'm sorry.

ok.

I haven't tried anything

I can

I can't understand the question.

This specific exercise is pretty hard compared to others.

[alpine crown]

I believe that's been discussed on the above forum thread I linked 😉

This task asks you to do something similar to the prior tasks but instead of using addition or multiplication to change the coordinates, you need to call a function.

Replace x, y = x1 + x2 y1 + y2 with x, y = some_function(x2, y2) or similar. Twice.
