Question: I am new to Javascript, and have been struggling to find a proper way to do what I'm looking for.
I have a heading "Page: Lastname Firstname"

What I want to do, is grab the last name ~only~ 
The last name will vary by length, and the page name will change as well but the format will always stay the same.

Answer: 
```
const pageTitle = 'Page: Lastname Firstname'
const lastName = pageTitle.split(' ')[1]

```

Basically we are splitting `pageTitle` string into Array, using  as separator. And then we are accessing second `[1]` element of given Array.
Considering the format will remain like `Name: fname lname`. There is no middle name of something else. You can use `split()` by `' '` and get second element.

```js
let str = "Page: Lastname Firstname"
console.log(str.split(' ')[1])
```
