In this blog series tutorial, I will be covering some of the basic JavaScript programming concepts.
This is geared toward beginners and anyone looking to refresh their knowledge.

Level 6 will cover:
- Use Bracket Notation to Find the Nth Character in a String
- Use Bracket Notation to Find the Last Character in a String
- Use Bracket Notation to Find the Nth-to-Last Character in a String
Use Bracket Notation to Find the Nth Character in a String
If we want to find which character of a string is sitting at a particular value, we again use bracket notation with the number position we want to find [Nth].
let player = "Druid";
console.log(player[2]);
"u"
Use Bracket Notation to Find the Last Character in a String
When we want to find the last character of a string, we can subtract one from the string's length.
let spell = "Fireball";
spell[spell.length - 1];
"l"
Use Bracket Notation to Find the Nth-to-Last Character in a String
Just as we did before to find the Nth and the last character in a string, we can combine the two to find the last to Nth character.
let enemy = "Goblin Mage";
let secondToLastLetter = enemy[enemy.length - 2];
console.log(secondToLastLetter);
"g"
