Function statement

Function statements are the preferred technique for defining functions in strict mode. A function statement begins with the function keyword, followed by:

• the function name;
• the parameters, in a comma-delimited list enclosed in parentheses;
• the function body, that is, the ActionScript code to be executed when the function is invoked, enclosed in curly braces.

For example, the following code creates a function that places the parameter into a trace() statement and invokes the function using the string hello as a parameter:

function traceParameter(aParam:String) {
     trace(aParam);
}
traceParameter("hello"); // Output: hello
