Javascript - alert bez "

Witam, da się w jakiś sposób wyświetlić alert ze stringiem bez użycia " albo '?
Chodzi mi o zamianę tych znaków na np. / co dałoby alert(/test/);

W jakim celu chcesz wyświetlać string bez podawania go w " "?

Zastanawiam się czy da się tak zrobić, a może przydać się w przyszłych projektach, w c++ było kiedyś coś takiego ale nie pamiętam jak się nazywało

Proszę bardzo
alert(/pff/)

String.prototype.replaceAll = function(str1, str2, ignore) {
    return this.replace(
        new RegExp(str1.replace(/([\/\,\!\\\^\$\{\}\[\]\(\)\.\*\+\?\|\<\>\-\&])/g,"\\$&"),
        (ignore?"gi":"g")),
        (typeof(str2)=="string")?str2.replace(/\$/g,"$$$$"):str2
    );
} 

eval("alert(/pff/)".replaceAll("/", "\""))

W C++ to się nazywa stringification, jednakże w ogóle nie oddaje to twojego przykładu

#include <iostream>
using namespace std;
#define str(x) #x" "
int main() {
	cout << str(Ala) str(ma) str(kota.) << endl;
	return 0;
}

tylko po co to komu? Obawiam się, że może chodzić o bardzo brzydką praktykę mieszania JavaScript z PHPem w jednym pliku...

Tak, da się:
