bd7123c9c450eddfaeb5bdef	Use Bracket Notation to Find the Nth Character in a String	1	https://scrimba.com/c/cWPVJua	18343

--description--

You can also use bracket notation to get the character at other positions within a string.

Remember that computers start counting at 0, so the first character is actually the zeroth character.

Example:

var firstName = "Ada";
var secondLetterOfFirstName = firstName[1]; // secondLetterOfFirstName is "d"

--instructions--

Let's try to set thirdLetterOfLastName to equal the third letter of the lastName variable using bracket notation.

Hint: Try looking at the example above if you get stuck.

--hints--

The thirdLetterOfLastName variable should have the value of v.

assert(thirdLetterOfLastName === 'v');

You should use bracket notation.

assert(code.match(/thirdLetterOfLastName\s*?=\s*?lastName\[.*?\]/));

--seed--

--after-user-code--

(function(v){return v;})(thirdLetterOfLastName);

--seed-contents--

// Setup
var lastName = "Lovelace";

// Only change code below this line
var thirdLetterOfLastName = lastName; // Change this line

--solutions--

var lastName = "Lovelace";
var thirdLetterOfLastName = lastName[2];
