The static Reflect
.get()
method works like getting a property from an object (target[propertyKey]
) as a function.
Reflect.get(target, propertyKey[, receiver])
target
propertyKey
this
provided for the call to target
if a getter is encountered.The value of the property.
A TypeError
, if target
is not an Object
.
The Reflect.get
method allows you to get a property on an object. It is like the property accessor syntax as a function.
Reflect.get()
// Object var obj = { x: 1, y: 2 }; Reflect.get(obj, 'x'); // 1 // Array Reflect.get(['zero', 'one'], 1); // "one" // Proxy with a get handler var x = {p: 1}; var obj = new Proxy(x, { get(t, k, r) { return k + 'bar'; } }); Reflect.get(obj, 'foo'); // "foobar"
