Q: What does the `Object.create()` method do?

The `Object.create()` method creates a new object with the specified prototype object. The new object inherits properties and methods from the prototype object. Choice of prototype while creating the Object instead of creating a constructor function is its main advantage To create an object that doesn't inherit from any prototype, you can pass `null` as the first argument to the `Object.create()` method. Object.create(proto) Object.create(proto, propertiesObject) // subclass extends superclass Rectangle.prototype = Object.create(Shape.prototype, { // If you don't set Rectangle.prototype.constructor to Rectangle, // it will take the prototype.constructor of Shape (parent). // To avoid that, we set the prototype.constructor to Rectangle (child). constructor: { value: Rectangle, enumerable: false, writable: true, configurable: true, }, }); With Object.create(), we can create objects with a designated prototype and also some properties. Note that the second parameter maps keys to property descriptors — this means you can control each property's enumerability, configurability, etc. as well, which you can't do in object initializers. o2 = Object.create( {}, { p: { value: 42, writable: true, enumerable: true, configurable: true, }, }, ); // This is not equivalent to: // o2 = Object.create({ p: 42 }) // which will create an object with prototype { p: 42 }
