What are unique constraints in Sequelize?
Unique constraints in Sequelize ensure that a column's values are unique across all records in a table.
How do I define a unique constraint in my model?
You can define a unique constraint by setting the unique: true option in your model's attribute definition.
Can I apply unique constraints to multiple columns?
Yes, you can create a composite unique constraint by using the unique option in the model's indexes array.
What happens if I try to insert a duplicate value?
If you attempt to insert a duplicate value, Sequelize will throw a validation error.
