A constant reference means an unchangeable object

Declaring an object variable final or const makes the object it refers to unchangeable, so its fields or elements cannot be modified.

Evidence patterns

Pattern 0: predict a mutation through a final/const reference

predicts an error

Item

const items = [1, 2];
items.push(3);
console.log(items);

Expected[1, 2, 3]

ResponseTypeError (or 'not allowed')

Discriminators

vs a slip. Consistent across items and the learner says const 'freezes' the value. A slip is a single wrong prediction.

Relations

conflicts_with: A constant reference does not make the referenced object immutable (external)
resolved_by: A constant reference does not make the referenced object immutable (external)
An object variable holds a reference; assignment copies the reference (external)
