Solution
The code will produce "true" on the console.
Here's the step by step explanation:
-
The variable 'a' is declared but not assigned a value, so it is 'undefined'.
-
The 'typeof' operator returns a string indicating the type of the unevaluated operand. In this case, 'typeof(a)' returns the string "undefined".
-
The 'if' statement checks the truthiness of the string "undefined". In JavaScript, all strings are truthy except for the empty string "". So, "undefined" is truthy.
-
Since the condition in the 'if' statement is truthy, the code within the 'if' block is executed, and "true" is logged to the console.
So, the correct answer is "true".
