Answer
ORMs like Sequelize or TypeORM map database tables to objects, simplifying queries and enforcing consistency.
Quick Answer
An ORM (Object-Relational Mapper) lets you interact with your database using JavaScript objects instead of raw SQL queries. Mongoose is the ORM for MongoDB; Sequelize and Prisma are popular for SQL databases. Benefits: type safety, schema validation, simpler query syntax. Trade-off: can obscure performance issues from inefficient generated queries.
