const abc = { val: 21 };console.log(Reflect.get(abc, "val") === 21);console.log(Reflect.get(abc, "x") === undefined);console.log(Reflect.get(abc, "y") === 21);Â
const array1 = ['neveropen1', 'neveropen2', 'neveropen3', 'neveropen4'];console.log(Reflect.get(array1, 3)); |
1 true true false neveropen4
Example 2: In this example, we will get the property of the object abc using the Reflect.get() Method in JavaScript.
