Easy Way to Understand How Optional Chaining Works in JavaScript and TypeScript Applications

This TypeScript programming tutorial goes into detail on how optional chaining can be utilized to streamline conditionals in an application. Practical ways that optional chaining can be used:
- Ensuring that data render attempts are only attempted after an application receives data from an API
- Allows for cleaner, more maintainable code since the conditionals can be built directly into the program instead of having to build 'guard' based conditionals.
- Preventing errors from occurring when a server sends unexpected data
