Warmup: Discussing Data Types in Daily Life
Prompt: Before we delve into JavaScript data types, let's have a discussion about the types of data we encounter in our daily lives.
Discussion Points: Can you think of examples where you use numbers, texts (strings), or yes/no (boolean) decisions in your daily routine? How do these examples relate to programming concepts, in your opinion? After a short discussion, we'll gather some thoughts and see how these everyday concepts translate into JavaScript.
Goals of the Activity:
Connect Daily Life to Programming: Helps in understanding abstract concepts by relating them to everyday experiences. Encourage Critical Thinking: Engages participants in thinking about how everyday actions translate into data types. Set the Stage for JavaScript Data Types: Creates a foundation for understanding the importance and use of different data types in programming.
