Get started coding! Use functions to create colorful patterns.
Variables store pieces of information, such as numbers or strings. Learn why variables are useful, how they’re created, and practice using them.
An array stores a list of multiple items, for example a list of groceries (an array of strings) or a list of ages (an array of numbers). Start using arrays and learn how to edit and access the items that arrays store.
If statements run code only if a certain condition is true. Learn how to create an if statement and control the flow of your code.
Learn how to use operators in coding, such as math operators (add, subtract, multiply, and divide) and logical operators (and & or).
Repetitive tasks can be boring! Learn how to use a for loop to run the same block of code multiple times.
Learn about other types of loops, such as a classic for loop, which runs a block of code a certain number of times.
Start using objects to store more complex data. Find out how objects differ from arrays, and learn how to edit and access the key-value pairs they store.
Climb the Mountain
In these final puzzles, you’ll use what you’ve learned to climb to the top of a mountain. Most of the puzzles don’t have starter code, so you’ll write your code from scratch!
