More Constraints
Explore how to implement different types of integrity constraints in front-end JavaScript applications. Learn to enforce frozen and read-only value constraints, understand object-level and type-level validations, and apply these within a model-view-controller structure for robust data management.
We'll cover the following...
Referential integrity constraints
A referential integrity constraint requires that the values of a reference property refer to an object that exists in the population of the property’s range class. Since we don’t deal with reference properties in this chapter, we’ll postpone the discussion of referential integrity constraints to the chapter on Associations](https://www.educative.io/collection/page/10370001/5397377793392640/5022490478247936).
Frozen and read-only value constraints
A frozen value constraint defined for a property requires that the value of this property must not be changed after it has been assigned. This includes the special case of read-only value constraints on mandatory properties that are initialized at object creation time.
