Solution:

script.js 
const planets = ['Earth','Mars','Saturn','Mercury','Jupiter','Venus','Uranus','Neptune'];
console.log(planets.join(', '));
console.log(planets.indexOf('Saturn'));

items should be separated by a comma AND a space.

It looks like you don't have the space.

.join(', ')

You only want to write the result of monthsString to the console. The join method is done in the previous step when you declare the variable monthsString and is not required when you log the output to to the console.

Try rewriting the code like this when you log the result to the console.

console.log(monthsString);

Looks like you need to do what Dan Parker suggested first by adding your space and then have to change the console.log line to what is typed above.
