Pixel says: "Coding is like telling a computer what to do. Let’s learn how to fix broken code to keep hackers out!"
A variable is like a box that holds information. In code, we use let to create a variable. For example, let name = "Pixel"; stores the name "Pixel".
Try it: Type password in the box below to store a password in a variable.
We can check how long a password is using length. For example, myPassword.length tells us the number of letters in the password.
Try it: Type length to check the password’s length.
If the password is too short, we tell the user it’s weak with a message like "Weak password!".
Try it: Type Weak password! to show a weak password message.
