When you define a named function in JavaScript, you must begin the function block with what?

• A. The keyword var
• B. curly brace { }
• C. The parentheses
• D. The keyword function followed by the function name

Answer: (D)

When you create a named function in JavaScript, you start with the keyword function and then the function’s name, followed by the parameter list in parentheses and the function body in curly braces. The declaration itself begins with function and the name, as in function myFunction() { ... }. The opening curly brace marks the start of the function body, but the very first part of the declaration is the function keyword and the name.

This differs from other patterns: using var would imply a function expression assigned to a variable (var myFunc = function() { ... };), not a plain named function declaration. Starting with a curly brace alone isn’t valid for introducing a function. The parameters come after the name, inside parentheses, not at the start.
