Which statement best describes the header of a named function in JavaScript?

• A. The keyword function followed by the function name
• B. The function name followed by parentheses
• C. The keyword var
• D. The curly braces enclose the body

Answer: (A)

In JavaScript, a named function declaration begins with the keyword function, immediately followed by the function’s name. That header portion introduces what’s being declared, then the parameter list in parentheses and the body inside curly braces complete the declaration. So describing the header as the keyword function followed by the function name matches how a function declaration starts, such as function myFunc(param) { ... }. The other options miss essential parts: omitting the function keyword means it isn’t a declaration, naming then just parentheses lacks the introducing keyword, var is used for variables, and the curly braces are used to enclose the body, not the header.
