How to delete a key (property) from an object in JavaScript?

Hello everyone! I just started learning JavaScript and encountered this problem. I have an object that contains user data: ```javascript let user = { name: 'Anna', age: 25, email: 'anna@example.com', password: 'secret123' }; ``` I need to send this object to the server, but before sending I want to delete the `password` field so as not to transmit it in plain text. I tried assigning `null` — it doesn't help because the key remains in the object. I've heard about the `delete` operator, but I'm not sure how to use it correctly. I also read that there is some method with destructuring — but that's pure magic to me. Please tell me how to correctly and safely delete a key from an object? Is there a difference between deleting regular properties and those that were inherited?
