It is not a perfect solution. Sometimes TLE.

e.g.

H E C P M E A O
K A D F O P J P
K D C B N G J H
G H P I C K N M
M O M D B O F A
B J N F C N F L
H B G I I L E L
J A I K G E L D

Your JavaScript looks like "Java"Script!

Perfection!
I was creating functions that combined parsers, but it never occured to me to do this

When i opened the full question page, i found that i had written it without tokenizing.

table is given as NATO

Why it works?

I think so. It's grammar is ambigious.

Another example:

fn add x y => x + y
add 1 2 + 1

;-)

Perhaps it is because the kata requires integer division, and JS uses floating-point numbers by default.

On the other hand, Kata itself does lack relevant random examples.

Oh my (__), thank you. I rely too much on the examples given below.

Wait for me to change my wording.

This is already mentioned in the description:

On each turn, you can move towards a square orthogonally or diagonally next to you, only if both of these two conditions hold:

• Your direction of movement is at most 90 degrees from the direction of the arrow under you
• Your direction of movement is at most 90 degrees from the direction of the arrow you're moving onto

Which part of this is not clear?

Good kata that took me two hours.

But, I don't think this kata has a good description.

In fact, when you try to move on a grid, you need to consider two things at the same time.

1. The direction you leave the grid cannot be opposite to the arrow direction of your current grid.
2. The grid you are going to cannot be opposite to the direction of your face when you come.

The description of the kata is vague about this point. So it took me an extra hour and a half.

it's not callback hell.

Haha, so kind of you.
I thought the author was not a native speaker of Chinese at first. I was just curious to ask how non-native speakers recognize and input Chinese characters.

You can google how to install an IME on your computer. Windows makes the process pretty easy, but that's how you can type in different languages' character set if you don't have specific keys for it on your keyboard.
