- JsonLogic enables sharing logic between front-end and back-end code and storing it in databases.
- It is a small, safe tool for delegating single decisions without loops, setters, or side effects.
- Rules follow a consistent format: {"operator": ["values"...]}, ensuring determinism and security without eval().
- Examples include simple comparisons, compound nested rules, and data-driven operations using the var operator.
- It supports handling static data, complex nested structures, and special cases like 'Always' and 'Never' rules.
