Ah, sorry, there was some minor issue in my browser. Resetting multiple times solved the issue.

No, it's not fixed.

Do you want me to delete this kata?

How would you suggest updating Javascript translation?

You need to throw RangeError, not return it.

Factorial of 13 should throw an exception of type ArgumentOutOfRangeException.

//the price of this juice bottle should is 7+5+7/3 = $6($6.333333...)

• So this juice bottle "should" or "is"?
• 7+5+7/3 is not 6, it's 14

I'm not sure there's any value in making description as difficult to understand as you did. Simple "write an insert statement" would be better.

What is factorial of 3 according to your code?

It's the "should should return the expected results" test that fails.

"should should return the expected results" test fails for me.

Wrote the query so that "Actual" is exactly the same as "Expected". One test still failing with the error:

expected true to respond to true? or perhaps you meant be true or be_truthy

Is something wrong with the kata or is it something I did?

My query returns exactly the same result as expected (compared "Actual" to "Expected"), but one test fails with the following error message:

expected true to respond to true? or perhaps you meant be true or be_truthy

Am I doing something wrong or is this caused by tests themselves?

Description mentions idx_number, tests expect row number.
Also description is way too complicated for what you're doing here.
