Line 21 - 'lisa', 'bart', 'homer' should be an array not individual strings.

['lisa', 'bart', 'homer']

Line 14 - console log you need to key the variable jsObject with the element at the ith position of the passed keys array.

console.log(jsObject[keys[i]])

Idk what your trying to do on line 18. If you remove it that should run.

There are different approaches, but following this approach, also replace <= with < in line 13

You don't need to run a for loop if you are passing only certain phrases:

const phrases = { a: 'Hello', b: 'World', c: '!' }

function printPhrases(one, two, three) { console.log(one + ' ' + two + ' ' + three) }

printPhrases(phrases.a, phrases.b, phrases.c)

If you don't want to be limited in your arguments you can use:

const phrases = { a: 'Hello', b: 'World', c: '!' }

const printPhrases = (...args) => { args.forEach(arg => console.log(arg.toString())) }

printPhrases(phrases.a, phrases.b, phrases.c)
