### Methods
|
|
|
|
|
|
|
|
|
|
Methods are a special kind of functions, they are functions called **from**
|
|
|
|
|
another value.
|
|
|
|
|
|
|
|
|
|
So that's what the `.` in `console.log` is for, we call the function `log`
|
|
|
|
|
**from** the `console`, so it will run its actions using the console.
|
|
|
|
|
|
|
|
|
|
Now every value types have methods in JS, for example, numbers have a special
|
|
|
|
|
`toFixed` method that allows you to specify how many decimals you want when you
|
|
|
|
|
convert them to string:
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
let thirdOf10 = 10 / 3
|
|
|
|
|
console.log(thirdOf10) // -> 3.3333333333333335 that's a lot of precision...
|
|
|
|
|
console.log(thirdOf10.toFixed(3)) // -> '3.333' that's quite enough !
|
|
|
|
|
console.log(thirdOf10.toFixed()) // -> with no argument, we get just '3'
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
So here in that second to last line we call `toFixed` from the value of the
|
|
|
|
|
variable `thirdOf10`, with the argument `3`, saying that we want 3 decimal
|
|
|
|
|
numbers in our string conversion.
|
|
|
|
|
|
|
|
|
|
Since they are functions, they can also return values.
|
|
|
|
|
|
|
|
|
|
### Instructions
|
|
|
|
|
|
|
|
|
|
One of the value with the most methods are strings, you can do a lot of things
|
|
|
|
|
with them.
|
|
|
|
|
|
|
|
|
|
For this exercise you will have to use the methods `toUpperCase` and
|
|
|
|
|
`toLowerCase` from the provided variable `message`.
|
|
|
|
|
|
|
|
|
|
- Create a `noCaps` variable of the value of `message` but in lower case.
|
|
|
|
|
- Create an `allCaps` variable of the value of `message` but in upper case.
