type
==============================
```
/**
* '===' behaves like '==' exept that no type conversion is done
*/
true == 1 // true because true is converted into 1 and then compared
"2" == 2 // true because 2 is converted into "2" and then compared
true === 1 // false
"2" === 2 // false
/**
* typeof
*/
typeof 50 === 'number' // true
typeof 'hej' === 'string' // true
typeof true === 'boolean' // true
typeof undefined === 'undefined'// true
typeof Math.sin === 'function' // true
