The docs appear to contain a small typo in the demonstration of using the existential operator in a chain of method calls.

[michaelficarra]

That's not a typo, it's one of the many existential operators:

• unary ?:
  • a? tests that a is in scope and a != null
• binary ?:
  • a ? b returns a if a is in scope and a != null; otherwise, b
• ?. and ?[ ]: soaked property access:
  • a?.b or a?['b'] returns a.b if a is in scope and a != null; otherwise, undefined
• ?( ): soaked function invocation:
  • a?(b, c) returns the result of calling a (with arguments b and c) if a is in scope and callable; otherwise, undefined
• ?=: existential assignment:
  • a ?= b assigns the value of b to a if a is not in scope or if a == null
