Object.create

The Object.create method creates a new object that inherits from the object passed as an argument. If a property is missing in the new object, it will attempt to access the property from the prototype object. This delegation process allows you to share properties and methods among multiple objects.

const parent = {
  name: 'Stacey',
  age: 35,
  heritage: 'Irish'
}
 
const child = Object.create(parent)
child.name = 'Ryan'
child.age = 7
 
console.log(child.name) // Ryan
console.log(child.age) // 7
console.log(child.heritage) // Irish

As the example above, the child object is created using the Object.create method and inherits properties from the parent object. When the child.heritage property is missing, it is looked up in the parent object and its value is inherited.
