The example in the text is wrong it should state get_hud([7,7], [3,2], [5,6,7]) instead of getHUD([7,7], [2,3], [5,6,7]), for tue characters displayed.

made some changes, description is still typescript specific though

It is especially important to include sample tests with even sizes. And it should be better explained in the description. For example, if the width is 4 then the correct position is 1 (not 2). The center is 2 but the digit position is 2 - 0.5 = 1.5 which is rounded down to 1.

• Description should be language-agnostic

• Example and sample tests should provide a test when row size is even length to comfront to the following requirement

  Should a screen dimension be even, they should be positioned at the middle most coordinate, rounded down.

• The parameter name screen_size should be screenSize

fixed

it shouldn't be stated, it's a puzzle

width and height can be 1 which makes numbers overlap, and it is not stated in which order they should be "rendered".

Actual/expected values are flipped in sample tests and their copy in the final tests.

Good catch

By the way, you should also calculate test and the error message before sample so users mutating the input array (for whatever reasons) won't affect the test results.

fixed

Well, if the tests are random we can't pattern match the results (they'd also be random assuming test inputs are strong) anyway, so good feedback becomes much more important.

I didn't realize the non-sample tests were supposed to have descriptive errors. I was under the impression that to avoid pattern matching failed tests wouldn't provide detailed reports.

fixed

expected [ Array(10) ] to deeply equal [ Array(10) ]

That's... not very helpful.
