Function equal

equal<K extends Primitive, V>(a: IMap<K, V>, b: IMap<K, V>): boolean
Checks if two IMap instances are structurally equal.

Two IMaps are considered equal if they have the same size and contain exactly the same key-value pairs. The order of entries does not matter for equality comparison. Values are compared using JavaScript's === operator.

Performance: O(n) where n is the size of the smaller map.
Type Parameters
- K extends Primitive
  The type of the keys.
- V
  The type of the values.
Parameters
- a: IMap<K, V>
  The first IMap instance to compare.
- b: IMap<K, V>
  The second IMap instance to compare.
Returns boolean
true if the maps contain exactly the same key-value pairs, false otherwise.
Example
```
const first = IMap.create<'a' | 'b', number>([
  ['a', 1],
  ['b', 2],
]);

const second = IMap.create<'a' | 'b', number>([
  ['b', 2],
  ['a', 1],
]);

const third = IMap.create<'a' | 'b', number>([
  ['a', 1],
  ['b', 3],
]);

assert.ok(IMap.equal(first, second));
assert.notOk(IMap.equal(first, third));
