Object() constructor

The Object constructor creates an object wrapper for the given value.

• If the value is null or undefined, it will create and return an empty object.
• Otherwise, it will return an object of a Type that corresponds to the given value.
• If the value is an object already, it will return the value.

When called in a non-constructor context, Object behaves identically to new Object().

new Object()
new Object(value)

value

Any value.

let o = new Object()
o.foo = 42

console.log(o)
// Object { foo: 42 }

The following examples store an empty Object object in o:

let o = new Object()

let o = new Object(undefined)

let o = new Object(null)
