Just as we can build a string over multiple lines out of string <dfn>literals</dfn>, we can also append variables to a string using the plus equals (<code>+=</code>) operator.

Sometimes you will need to build a string, <a href="https://en.wikipedia.org/wiki/Mad_Libs" target="_blank">Mad Libs</a> style. By using the concatenation operator (<code>+</code>), you can insert one or more variables into a string you're building.
Example:
```js
var ourName = "freeCodeCamp";
var ourStr = "Hello, our name is " + ourName + ", how are you?";
// ourStr is now "Hello, our name is freeCodeCamp, how are you?"

<dfn>Bracket notation</dfn> is a way to get a character at a specific <code>index</code> within a string.
Most modern programming languages, like JavaScript, don't start counting at 1 like humans do. They start at 0. This is referred to as <dfn>Zero-based</dfn> indexing.
For example, the character at index 0 in the word "Charles" is "C". So if <code>var firstName = "Charles"</code>, you can get the value of the first letter of the string by using <code>firstName[0]</code>.
Example:
```js
var firstName = "Charles";
var firstLetter = firstName[0]; // firstLetter is "C"
```

You can use the same principle we just used to retrieve the last character in a string to retrieve the Nth-to-last character.
For example, you can get the value of the third-to-last letter of the <code>var firstName = "Charles"</code> string by using <code>firstName[firstName.length - 3]</code>
Example:
```js
var firstName = "Charles";
var thirdToLastLetter = firstName[firstName.length - 3]; // thirdToLastLetter is "l"
```
</section>
## Instructions
<section id='instructions'>
Use <dfn>bracket notation</dfn> to find the second-to-last character in the <code>lastName</code> string.
<strong>Hint</strong><br>Try looking at the <code>thirdToLastLetterOfFirstName</code> variable declaration if you get stuck.
<strong>Hint: </strong> Try looking at the example above if you get stuck.
