Kata should really ask to extend the prototype non-enumerably. Teach good habits.

Updated tests and description to explicitly fail input mutation. Random tests used to be implicitly vulnerable to that.

ETA: also added fixed tests with falsy expected values, because some solutions were buggy that way.

A neat little kata — thanks for putting this together! It’s simple on the surface but a good reminder of how extending prototypes can make arrays more expressive and readable.

select table schema

age_min (minimum of ages)

age_max (maximum of ages)

Because the instructions ask for the aliases being age_min and age_max

why can't we use min_age and max_age for the alias?

When running the psql postgres CLI, you do use a semicolon to let the CLI know to start processing the statement.

What happend to your code??? Chill out bro :)

What about a1 = ['te st'] and a2 = ['te', 'st']?

This is brilliant thanks

Wow mine looks nothing like this!
