Hi William!

This passes both:

const planets = ['Earth','Mars','Saturn','Mercury','Jupiter','Venus','Uranus','Neptune'];

const joinedPlanetsStr = planets.join (', '); 
console.log (joinedPlanetsStr);

const pos = planets.indexOf('Saturn');
console.log(pos);

This also passes:

const planets = ['Earth','Mars','Saturn','Mercury','Jupiter','Venus','Uranus','Neptune'];

console.log ( planets.join (', ') );

console.log( planets.indexOf('Saturn') );

I hope that helps.

Stay safe and happy coding!
