Please

• read Docs. yes, all of them.
• read test suites of kata you solved.
• head over to Discord#help-authoring for review of your Draft
• publish your kata in one language. when specs and implementation have stabilised, you can add translations.

You're making all the usual first time author mistakes.

in JS it's not. you may have a JS version you didn't intend to have.

• description should be language-agnostic
• examples should not be on one line

⦁ Do not mutate the input list.

• is that actually tested? if you specify things, you have to test them.

• base is not a good name for the parameter. "base" has a well-defined, completely unrelated meaning.
• "strict sequence" is not a well-defined term. I think you mean "arithmetic progression", but you'd still have to define the step as 1.

• Needs sample test cases
• Needs random tests
• Full tests need proper labels
