Hello, Words! 👋
Hi there, young coder! 🌟 Today we learn about strings.
A string is just text that the computer can read. Like your name, a magic word, or "Hello!" 🎉
console.log("Hello!")Quotes are Magic Bags 🎒
To make a string, we wrap our text in quotes. Quotes are like little bags that hold your words!
Look: "cat" is a string. The cat is safe inside the quotes! 🐱
console.log("cat")Say Your Name 🧒
Let us put YOUR name in a string. Try changing "Sam" to your own name!
The computer will say it back to you. 🗣️
console.log("My name is Sam")Numbers Can Be Strings Too 🔢
Even numbers can hide in quotes! "123" is a string of text, not a math number.
If it has quotes, it is a string. Easy! 😄
console.log("123 is a string")Single or Double Quotes 👯
You can use double quotes "like this" OR single quotes 'like this'.
Both make strings! Pick your favorite. 🎈
console.log('I love single quotes')Saving a Word in a Box 📦
We can save a string in a box with a name. We call this box a variable.
Here we put "treasure" in a box called word. 💎
let word = "treasure"
console.log(word)Strings Can Be Long 📜
A string can be one word OR a whole sentence!
"I have a pet dragon that loves cookies" is one big string. 🐉🍪
console.log("I have a pet dragon that loves cookies")Empty String 🫙
A string with nothing inside is an empty string. It looks like this: ""
It is like an empty bag. Still a bag, just no words yet! 🛍️
let nothing = ""
console.log("This is empty:", nothing)Spaces Count! ␣
Spaces inside quotes are part of the string too!
"hi" and "hi " are a little different. The second one has a space at the end. 👀
console.log("space matters")Strings With Emojis 🦄
You can even put emojis in your strings! They are part of the text too.
How fun is that? 🌈🦄🍭
console.log("I love coding 🦄🌈")You Made a String! 🎉
Wow! You now know what a string is. Let us make a happy message string together!
Change the words and make it YOURS. 💖
let happy = "Coding is fun!"
console.log(happy)Quick Check ✅

Yay, You Did It! 🏆
