It is necessary to replace one variable with another one and change the second one. Like this:

a = b; b = c;

  • If you swap places, try this: [inventory[3], inventory[4]] = [inventory[4], inventory[3]]; Although, this method will not work if, apart from color , there are other properties and they do not need to be affected - Deonis
  • Thank you very much, do not tell me now why my method does not work? - Dmitriy

Instead

 inventory[3] = inventory[4];

Need to

 inventory[3]['color'] = inventory[4]['color'];
  • So I need to completely replace inventory [4] to the place of inventory [3] - Dmitriy
