Answer

A JavaScript object is a collection of properties with an associated prototype. • Property keys are strings or symbols. • A property can be a data property or accessor property. • Objects have identity, so separate object instances are not strictly equal.

Example

Code

const user = { name: 'Maya', active: true };
console.log(user.name);

Output

Maya
