Pattern: Empty Object() constructor call

Issue: -

Description

Using the Object constructor to create empty objects is discouraged in favor of object literal notation. The only valid use case for Object() or new Object() is when intentionally wrapping a value to create an object.

Examples

Example of incorrect code:

const obj = new Object();
const dict = Object();

function createObj() {
  return new Object();
}

Example of correct code:

const obj = {};
const dict = Object.create(null);

// Wrapping values is ok
const str = Object("foo");
const num = Object(123);

function isObject(value) {
  return value === Object(value);
}
