Check out this amazing tip on how to conditionally chain query clauses! 💡 Let's level up our coding skills together! 🔗💻 #codingtips#queryclauses#programming101
The Bottom Line:
You can be a coder without being a programmer (typing without a plan).
But you can’t be a programmer without knowing how to code.
Stop just "learning to code"—start learning how to build! 🚀 #TechTips#Coding#Programming101
Basic Coding Concepts introduce beginners to variables, loops, conditionals, and functions, building a strong foundation for problem-solving and logical thinking in programming and digital innovation.

The correct answer is C) An error in code! 🐛💻
Bugs cause unexpected results, and finding them is called debugging. It's the daily reality of every coder!

🎯 DATA TYPES: JavaScript's Hidden Grammar
You can't speak a language if you don't know its nouns. JS has 7 1 core "types" of data.
▶️PRIMITIVES (The simple, direct values):
▶️String: "Hello, World!" (text)
▶️Number: 42, 3.14 (all numbers, floats & ints)
▶️Boolean: true, false (yes/no logic)
▶️null: Intentional "no value"
▶️undefined: Variable declared, but no value assigned yet
▶️Symbol: Truly unique identifiers (ES6 magic)
▶️BigInt: For numbers LARGER than 2^53 - 1 (when precision is key!)
REFERENCE (The complex, interconnected values):
▶️Object: { name: "Alice" } (key-value pairs)
▶️Array: [1, 2, 3] (ordered lists)
▶️Function: () => {} (code that does stuff, but it's also an object!)
typeof null returns "object". It's a historical bug! Don't let it fool you.

Follow-up to my Rails association extensions post.
I often extend `has_many` with statistics methods. This example does two COUNT aggregations and adds columns to the result.
But here's the key: I don't want BookingOption to behave differently based on which columns exist in the query result.
Code should always be explicit.
Solution: Inherit `BookingOptionWithStats` from `BookingOption` and explicitly cast results to the new class.
No surprises. No implicit behavior.
A screenshot of the `BookingOptionWithStats` class original post are in the thread 👇.
