+# Debugging 2
+
+## Examples
+
+Work through some examples and/or homework assignments together with the
+students.
+
+## Creating variables
+
+Inlining is great but not when debugging.
+
+TODO Explain how to extract function call results into variables and why that is
+useful.
+
+## ESLint
+
+TODO
+
+## Simplifying input
+
+Often a program is big, and the defect not obvious. The program fails but you
+have no clue where to start because the program state is too big to reason
+about. Instead of frantically using `console.log` everywhere (which might
+sometimes work) we take one step back. We first simplify the input so that we
+get to a manageable state, something we can reason about. If our program still
+fails we can continue debugging. If it doesn't we need to pick different input.
+
+*TODO Write a buggy program that uses a lots of input and state.*
+
+  - Maybe a sorting algorithm?
+  - Something that uses a stack
+  - Filtering algorithm (something that filters on a certain string)
