Grabbing Treasures 🤲
Hi, treasure grabber! 🌟 How do we get ONE item out of a list?
We use its position number inside [ ]! 🔢
let treasure = ["gold", "gem", "crown"]
console.log(treasure[0])Counting Starts at Zero! 0️⃣
Surprise! Lists count from 0, not 1!
The first item is at position [0]. 🤯
let pets = ["cat", "dog", "fish"]
console.log(pets[0])The Second Item 1️⃣
The second item is at position [1]!
0 is first, 1 is second. A little tricky but fun! 🎈
let pets = ["cat", "dog", "fish"]
console.log(pets[1])The Third Item 2️⃣
The third item is at position [2].
See the pattern? Position is always one less than the count! 🪄
let pets = ["cat", "dog", "fish"]
console.log(pets[2])Grabbing Gold 🪙
Let us grab the first treasure from our chest!
Position 0 is the gold. 🪙
let treasure = ["gold", "gem", "crown"]
console.log("I found: " + treasure[0])Pick Your Favorite 💖
Use the position number to pick any item you want!
Change the number to grab a different one. 🎯
let snacks = ["candy", "cookie", "cake"]
console.log(snacks[2])Numbers in a List 🔢
We grab numbers from a list the same way!
Position 0 gets the first number. 🧮
let scores = [10, 20, 30]
console.log(scores[1])Counting Friends 🧒
Let us say hi to the first friend in our team list!
Position 0 is the team captain. 👋
let team = ["Sam", "Lily", "Max"]
console.log("Captain: " + team[0])Out of Range 🚫
If you ask for a position that does not exist, you get undefined!
That means "nothing there". Our list only goes to position 2 here. 🤷
let pets = ["cat", "dog", "fish"]
console.log(pets[5])The Last Item 🏁
The last item is at position length - 1!
If there are 3 items, the last one is at position 2. 🎯
let colors = ["red", "blue", "green"]
console.log(colors[colors.length - 1])Your Turn to Grab 🧒
Change the position number to grab different treasures!
Remember: counting starts at 0. 🔢
let chest = ["map", "key", "coin", "ring"]
console.log(chest[2])Quick Check ✅
Position question! You can do it! 🎯
