Introduction

A program is a set of instructions. Start with one instruction that prints a message. Run it, change the message, and run it again. The edit–run–observe loop is how programmers explore ideas.

Syntax & example

console.log("Hello, CuroCube!");

Expected output

Hello, CuroCube!

Common mistakes

  • Using a variable before assigning a value to it.
  • Mixing text and numbers without converting deliberately.
  • Skipping an empty input or a boundary value when testing.

Practice

Change the greeting to include your name.
