Different data types
Data and Logic · Working
What is this skill?
Understanding different data types means knowing the difference between strings, numbers, booleans, arrays, and objects. This is essential for handling user input and building logic.
Why is it important?
- Correct comparisons – Comparing "1" (string) and 1 (number) behaves differently
- Form handling – Form inputs are always strings; you may need to convert them
- Conditional logic – Booleans are essential for branching
- Data structures – Arrays and objects let you manage lists and complex data
