Use Case

As a... user
I want...  to only cache hex string if toHexString is called or a hex string is passed in the constructor
So that... performance is optimized

Unknowns

• Consider caching bytes and other properties in ObjectId lazily as well

Dependencies

• Generic deep equality checkers such as LODASH are no longer safe for users to use

Acceptance Criteria

Implementation Requirements

• When ObjectId.cacheHexString === true, lazily cache the hex string. This means only cache the hex string if:
  • constructor is passed in a hex string
  • objectid.toHexString() is called
• Make the ObjectId.__id property fully invisible to users by using the # keyword

Documentation Requirements

• Document that generic deep equality checkers are no longer safe to use with ObjectId, use the built-in equality checker for ObjectId instead

Follow Up Requirements

• N/A
