Can you list ways to use the Object construct in JavaScript?

In JavaScript, the Object construct is used in several main ways:

1. Creating objects:

const obj1 = new Object();
const obj2 = {};

2. Declaring properties and methods:

const obj = {
  name: 'Alice',
  greet() { console.log('Hello'); }
};

3. Using static Object methods:

• Object.keys(obj) — returns an array of the object's keys.
• Object.values(obj) — returns an array of the object's values.
• Object.assign(target, ...sources) — copies properties from sources to the target object.
• Object.freeze(obj) — makes the object immutable.

4. Property checking:

if (Object.hasOwn(obj, 'name')) { /* ... */ }

5. Setting the prototype:

const proto = { greet() { console.log('Hi'); } };
const obj = Object.create(proto);
obj.greet(); // Hi

Thus, Object is a fundamental building block for working with objects in JavaScript.
