Describe your experience with ORM tools in projects.

In Node.js projects, I have used ORM tools such as Sequelize and TypeORM to simplify database interactions. ORM allows describing data models as classes and objects, which makes creating, reading, updating, and deleting records easier without writing raw SQL queries.

For example, with ORM, you can define a user model and perform operations with it:

const User = sequelize.define('User', {
  username: Sequelize.STRING,
  birthday: Sequelize.DATE
});

// Creating a new user
await User.create({ username: 'john', birthday: new Date(1990, 1, 1) });

// Finding a user
const user = await User.findOne({ where: { username: 'john' } });

ORM helps keep the code cleaner and more portable across different DBMSs, as well as manage migrations and relationships between tables.
