The code will output 'truthy'. The ternary operator (? :) first evaluates the condition before the question mark. An empty array ([]) is a truthy value in JavaScript, so when converted to a boolean in this context, it becomes true. Since the condition is true, the ternary operator returns the value after the question mark and before the colon, which is the string 'truthy'. The ternary operator is a concise way to write an if-else statement and is widely used in JavaScript for conditional assignments and expressions.
