LangChain - LangGraph for Stateful Agents

Given this routing setup:

conditions = [lambda ctx: ctx['age'] > 18, lambda ctx: ctx['age'] <= 18]
routes = ['adult_node', 'child_node']
ctx = {'age': 20}

Which node will the graph route to?

Aadult_node

Bchild_node

CNo routing occurs

DBoth nodes run

Step-by-Step Solution

Solution:

Step 1: Evaluate conditions with ctx
ctx['age'] is 20, so first condition ctx['age'] > 18 is True.
Step 2: Determine routing based on first True condition
Graph routes to 'adult_node' because first condition is True.
Final Answer:
adult_node -> Option A
Quick Check:
Condition True routes to adult_node [OK]

Quick Trick: First True condition decides route [OK]
