+## Definition
+- Pure mathematical functions
+- Declarative paradigm
+	- Instead of writing step-by-step, we define the desired outcome
+- Immutable data
+- => No/Less side effects
+- Programs are easier to verify
+	- We can mathematically prove the algorithms
+
+
+## Lazy vs. Strict
+- Calculations are delayed until the results are actually needed
+
+### Example
+Imagine a list of numbers, but you only need the first one that meets a condition. With lazy evaluation, the program stops processing the list as soon as it finds the result, instead of checking every number.
