How to remove a property from a JavaScript object?

Given an object:

let myObject = {
  "property": "value",
  "another-property": "another-value"
};

To remove a property from an object (mutating the object), you can do it like this:

delete myObject.property; // true
// or,
delete myObject['property']; // true
// or,
var prop = "property";
delete myObject[prop]; // true

delete myObject.invalidproperty; // false

The delete operator is used to remove these keys, more commonly known as object properties, one at a time. delete operator returns false when a property can not be deleted.
