Javascript equivalent of PHP ${"randomName"}

[h3rm3s]

So, I recently discovered that you can generate new variables in PHP by doing something like

${"randomString"} = true;

//or something like this:

$counter = 0;

while($counter < 10)
{
	${"var_" . $counter} = "This is a variable with a by PHP generated name";
	$counter = $counter + 1;
}

This allows me to generate new variables with custom names. Is there something similar in Javascript?

can't you just like

var randomString = 5;

???

Yes, of course I can. But using a thing called 'variable variables' you can generate variables, with names, generated by code. Look at the link if you want to know more. I'm not very good at explaining this.

No, the correct way would be to use an array.

 

PHP's variables variables should never been a thing!

Oh ok, so I should just use an array. Just out of curiosity, what's wrong with variables variables?

If it's a global variable, you can access it using 

window[randomName], but if it's a local variable, I think you have to use eval if you want to use an arbitrary name, unless you just add them to an object instead.
