True if this and the other Collection have value equality, as defined
by Immutable.is().
Note: This is equivalent to Immutable.is(this, other), but provided to
allow for chained expressions.
Computes and returns the hashed identity for this Collection.
The hashCode of a Collection is used to determine potential equality,
and is used when adding this to a Set or as a key in a Map, enabling
lookup via a different instance.
const { List, Set } = require('immutable');
const a = List([ 1, 2, 3 ]);
const b = List([ 1, 2, 3 ]);
assert.notStrictEqual(a, b); // different instances
const set = Set([ a ]);
assert.equal(set.has(b), true);
Note: hashCode() MUST return a Uint32 number. The easiest way to
guarantee this is to return myHash | 0 from a custom implementation.
If two values have the same hashCode, they are not guaranteed
to be equal. If two values have different hashCodes,
they must not be equal.
Note: hashCode() is not guaranteed to always be called before
equals(). Most but not all Immutable.js collections use hash codes to
organize their internal data structures, while all Immutable.js
collections use equality during lookups.
