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)

In JavaScript, a named function declaration begins with the reserved keyword that signals a function, immediately followed by the function’s name. This sets up the function’s identifier and tells the parser that a function is being defined. The typical syntax is function myFunction(params) { ... }, where the keyword function starts the header, the name identifies the function, and the parameter list in parentheses comes next, with the body opening at the opening curly brace. That’s why starting with the keyword function and then the function name is the correct way to begin a named function. The other elements you might see—like var (which would declare a variable), the parentheses (which come after the name to list parameters), or the curly brace { (which opens the function body)—do not themselves start the function declaration header.
