Variable assignment question.

All I really need is confirmation for this, but is this:

var variable1 = variable2 = variable3 = value;

The same as and just as legal as this?

var variable1 = value;
var variable2 = value;
var variable3 = value;

Legal? Yes, I think. But it is not the same. What you get is equivalent to

var variable1 = value;
variable2 = value;
variable3 = value;
Variables don't have the same scope.

But that ^ would return a warning saying the two latter ones were assigned a value without being declared, wouldn't it?

I don't get that error with var = var1 = var2 = var3 = value;.

In most cases, you don't have to declare a variable in JavaScript using the var keyword.

However, it is recommended that you do declare them using the var keyword.

Also, you can declare variables in the following manner:


var varaible1 = "Something",
variable2 = "Something",
variable3 = "Something",
variable4 = "Something";


Good luck.
