Hello, thanks for this course!!

Doing the course I found a problem when I tried to used console.log:

11:5 error Unexpected console statement no-console
13:5 error Unexpected console statement no-console

Someone help me out with this problem and explained to me that the issue was caused by the library ESlint, specifically, the rule no-console that comes with "eslint:recommended" rules.

I don't know if this is intended, but it prevents working with the examples and see the results in the console.

thanks :)

The code shown in the explanation video is not in fact immutable.

Incorrect code:

console.log([
  ...drinks.splice(0, index),
  'Mojito',
  ...drinks.splice(index - 1),// side note: the -1 index correction is only needed as a result of the first splice mutating the original array
]);

Correct code:

console.log([
  ...[...drinks].splice(0, index),
  'Mojito',
  ...[...drinks].splice(index),
]);

Explanation:
As splice mutates the original array, before the spread operator spreads it, the original array gets mutated nevertheless. Solution: copy original array with spread operator, splice it, then spread the result.
