What's the single biggest reason to use $parameters?

Cached query plans + injection safety

Parameters are required by Cypher

Cypher cannot handle literals over 100 chars

UNWIND and Parameters

UNWIND a list into rows. ALWAYS use $params — never string-concat into a query.

UNWIND a list into rows. ALWAYS use $params — never string-concat into a query.

Driver parameters are how Neo4j gives you both safety (no injection) and speed (the planner caches the query plan keyed on shape).

Use the prompts below to anchor unwind and parameters to a real graph you own.

›Pick a graph workload you've shipped — where would *unwind and parameters* have changed the design?
›What's the smallest version of this pattern you could prototype on a real dataset next sprint?
›What is the most likely *misuse* of this idea, and how would you catch it in a model or query review?
