indicating whether or not the property was successfully deleted. It is almost identical to the non-strict delete
operator.

Using Reflect.deleteProperty()
let obj = { x: 1, y: 2 } Reflect.deleteProperty(obj, 'x') // true obj // { y: 2 } let arr = [1, 2, 3, 4, 5] Reflect.deleteProperty(arr, '3') // true arr // [1, 2, 3, undefined, 5] // Returns true if no such property exists Reflect.deleteProperty({}, 'foo') // true // Returns false if a property is unconfigurable Reflect.deleteProperty(Object.freeze({foo: 1}), 'foo') // false
