so i'm trying wrap head around different ways create object. i came accross protoype pattern creating objects. now wrote 2 functions below can't see functional difference between both be? when use constructor pattern , when use prototype pattern? constructor pattern function fruit(){} fruit.color = "yellow", fruit.fruitname = "banana", fruit.nativeto = "somevalue" prototype pattern function fruit(){} fruit.prototype.color = "yellow", fruit.prototype.fruitname = "banana", fruit.prototype.nativeto = "somevalue" reusability of components... constructor when create new constructor create new instance of , importantly change made instances affect them , not others. prototype when create new object using prototype reuse logic , change prototype chain affect else. this nice explanation: javascript prototypes , instance creation when use each pattern based on needs - ambiguous answer never...
