| Aug 4, 2020 at 2:01 | comment | added | Jayce444 | @JuanMarco spread only makes a shallow copy. Only works if the array is composed entirely of primitives like strings, numbers or booleans. You have an array of objects, so it won't do a deep copy. | |
| Aug 3, 2020 at 12:17 | comment | added | adiga | @JuanMarco spread syntax creates a copy of the array. The objects inside it are still the same in the copy and the original array. | |
| Aug 3, 2020 at 12:16 | comment | added | Juan Marco | I'm not mutating the state @adiga, I'm making a copy of the state using spread syntax. I then make the change and update the state. See here for details. | |

currentItems[index].quantity += 1 mutates the state. const currentItems = [...stock] only creates a shallow copy of the array.

| Aug 2, 2020 at 20:17 | comment | added | Juan Marco | The functioning snippet is under "Show code snippet" @pacmaninbw | |
| Aug 2, 2020 at 20:06 | comment | added | pacmaninbw♦ | Welcome to Code Review, where we review working code and provide suggestions on how that code can be improved. This question without the functioning snippet is off-topic.Rather than hiding the snippet I would leave it fully open all the time. | |
