Why can"t get and set be used with writable in
Object.defineProperty () will report an error
var obj = {}
Object.defineProperty(obj, "name", {
configurable: true,
enumerable: true,
writable: true,
value: 2,
set(value) {
name = value
},
get() {
return value
}
})
obj.name = 2
console.log(obj.name) if the code above, it will report Cannot both specify accessors and a value or writable attribute this error
solve
if a descriptor does not have either value,writable,get or set keywords, it is considered a data descriptor. If a descriptor has both (value or writable) and (get or set) keywords, an exception will be generated. -taken from the original words of MDN.
probably means that it is impossible to set an attribute that can read and write it normally, and you can set a layer of getter/setter on it to access and rewrite it.
