Needs test with template with multiple {{name}} ( or similar ). Some solutions might replace only one name.

Thanks for the neat kata!
Just a quick note: there’s a small typo in the test cases — “parram” should be “param.”
Also, the phrase “have to filled by two parram function pattern” could be clearer as “should be filled by a two‑param function pattern.”
Great concept overall!

So good, thanks!

Nice kata!

Python & Javascript & Ruby:

• Should test for non-existent tag names in the random tests as well

• Should test for random tag names in the random tests instead of just "{{name}}" and "{{stuff}}" / "{{thing}}"

python new test framework is required. updated in this fork

Sorry, my bad. Thank you for your response.

No, your code is wrong, read the error message:

{ firstName: 'Albert',
  lastName: 'Einstein',
  occupation: 'physicist' }
Expected: 'Albert Einstein likes ', instead got: 'Albert Einstein likes {{interests}}'

When key doesn't exist in the map, put there empty string.

Your function is returning 'Albert Einstein likes {{interests}}'

Wrong test for {{firstName}} {{lastName}} likes {{interests}} when do on JS, there is wrong binding between template value and obj keys. Instead of 'interests' you expect 'occupation', what is wrong.
