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.
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 :)
