LEVEL UP with JavaScript! LVL 6

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.

See the Previous Level Here

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"
