There should also be fixed and random test cases of bracket mis-swapped, like ][ and []1, 2, 3][

should have fixed tests like [[1, 2] [3, 4]] ---> null, but the reference solution would not handle it

7 years passed, just 91.. Nice kata

For simplicity, only number literals appear in the array

• Hexadecimal literals with lowercase letters are not tested
• Octal literals are not tested
• Binary literals are not tested (these are not supported by all languages but I'll mention it anyway)
• Floats are not tested

Considering how weak the tests are in this regard, IMO it'd be easier to get rid of this specification and use decimal integers only.

These cases should be tested:

parseArray(",[]") === null
parseArray("[],") === null

No random tests with hexadecimals and decimals in scientific notation.

Math markup could be used to present formulas.

After three years ?!?

Would it make sense to include invalid test cases such as "[4 2]" or "[abc]"? Or are such cases ruled out by the fact that the content of the array is supposed to be limited to number literals?

Thank you, Alien-San. :]

Is there anybody out there ?!?
