JavaScript Optional Chaining in 5 Minutes (No more "cannot read property of undefined"!)

Save yourself some JavaScript code by using Optional Chaining. Optional Chaining can help you help work with data that might be inside of nested objects. You longer have to check that each object "along the chain" exists. This means no more "cannot read property x of undefined"....YAY!
