What you’ll learn

Explain what coding and algorithms are and how computers follow instructions.Coding is giving computers step-by-step instructions in a language they understand. An algorithm is an ordered list of steps, like a recipe. Computers run code line by line and do exactly what they are told. Mistakes are called bugs, and fixing them is debugging.
Describe loops, if-statements, coding languages, and where code is used.Loops let computers repeat tasks, and if-statements let programs make decisions. Coders use different languages like Scratch, Python, and JavaScript. Code powers games, apps, cars, and more, and anyone can learn it with curiosity and practice.
