Welcome to Bubble

Bubble is a fun, easy-to-learn programming language designed for beginners. Let’s dive in and start coding with Bubble!

Your First line of Bubble Code

In Bubble, you can print something on the screen with the say command. Add the text you want to show by using quotations.

say "Hello, World!"

Run this code and you’ll see “Hello, World!” printed to the console. Congratulations, you just wrote your first Bubble program!

Variables

Variables are like places where you can save information. For example, you can save the value of a number to a variable. In bubble, we can use the set keyword.

set x to 5

We can print the values of x and y using the say command

say x

You can also combine variables and strings using the plus operator:

set greeting to "Hello, "
set name to "Alice"
say greeting plus name # Output: Hello, Alice

Conditionals

Bubble supports conditional statements to make decisions in your code. Use if, else, and end keywords to define the structure:

set x to 2
if x is greater than 5
  say "x is greater than 5"
else
  say "x is not greater than 5"
end if

User Input

Getting user input is simple with the input function. Here’s a little number guessing game:

set name to input "What is your name? "
say "Hello, " plus name plus "! Let's play a guessing game."

set secretNumber to 7
set guess to input "Guess a number between 1 and 10: "

if guess is equal to secretNumber
    say "Correct! You guessed it!"
else
    say "Sorry, that's not it. The number was " plus secretNumber
end if

say "Thanks for playing, " plus name plus "!"
