Syntax

Reflect.get(target, propertyKey[, receiver])

Parameters

target

The target object on which to get the property.

propertyKey

The name of the property to get.

receiver Optional

The value of this provided for the call to target if a getter is encountered. When used with Proxy, it can be an object that inherits from target.

Return value

Description

The Reflect.get method allows you to get a property on an object. It is like the property accessor syntax as a function.

Examples

Using Reflect.get()

// Object
let obj = { x: 1, y: 2 }
Reflect.get(obj, 'x')  // 1

// Array
Reflect.get(['zero', 'one'], 1)  // "one"

// Proxy with a get handler
let x = {p: 1};

let obj = new Proxy(x, {
  get(t, k, r) {
    return k + 'bar'
  }
})
Reflect.get(obj, 'foo')  // "foobar"

//Proxy with get handler and receiver
let x = {p: 1, foo: 2};
let y = {foo: 3};

let obj = new Proxy(x, {
  get(t, prop, receiver) {  
    return receiver[prop] + 'bar'  
  }
})
Reflect.get(obj, 'foo', y) // "3bar"
