## Summary

- There are two types of numbers in JavaScript:
  - **Integers**: Discrete numbers like `1`, `2`, `3`, `-1`, `-2`, `-3`, etc;
  - **Floats** *(Floating-Point Numbers)*: Numerical values that have a decimal in them (e.g., `3.14`, `-0.5`).

- **Booleans** are values that can be either `true` or `false`;

- **Null** (`null`) values represent the intentional absence of data.
