The video tutorial covers adding and modifying properties in JavaScript objects, focusing on changing a 'name' property to 'first name' and adding a 'last name'. It explains object destructuring, highlighting the need to use exact property names when assigning object properties to variables. The tutorial also demonstrates logging output to the console and compiling TypeScript code. Emphasis is placed on the importance of matching property names in objects to avoid errors.

• It is removed.

• It is left unchanged.

Which brackets are used for destructuring an object?

Why is it important to use exact property names when destructuring?

• To ensure the code runs faster.

• To allow for more properties to be added.
