# Object typification in JavaScript

Objects have their own data type called `'object'`. Check it with the operator `typeof`:

`console.log(typeof {}); // shows 'object'`

Without running the code, determine what will be output to the console:

`console.log( typeof {x: 1, y: 2, z: 3} );`

Without running the code, determine what will be output to the console:

`console.log( typeof {} );`

Without running the code, determine what will be output to the console:

`let obj = {x: 1, y: 2, z: 3}; console.log( typeof obj );`

Without running the code, determine what will be output to the console:

`let obj = {x: 1, y: 2, z: 3}; console.log( typeof obj['x'] );`
