=====(3)
var showText3 = function (lineNumber3) { console.log('Testing Text: ' + lineNumber3); }

=====(4)
(function (lineNumber4) { console.log('Testing Text: ' + lineNumber4); }
)('Method 4');

=====(5)
(function (lineNumber5) { console.log('Testing Text: ' + lineNumber5); }
('Method 5'));

void function (lineNumber6) {
    console.log('Testing Text: ' + lineNumber6);

=====Note

(1)為函數陳述式, 不管放在前或後, 都可以被執行. 其它為函數運算式則需要先建立後才能呼叫.

showText7('Method 7');

function showText7(lineNumber7) {

    console.log('Testing Text: ' + lineNumber7);

}
