Declare mutliple variables in for loop

Question

I am trying to declare multiple variables in a for loop but the way I am doing it its not working, I tried to search for similar questions but couldnt find...

 for (var n = 0;  n < 10; n++) 
   {  
        var b + n = document.getElementById("b" + n);               
   }

So you want to end up with variables named `b0`, `b1`, `b2`, ... `b9`? — j08691, Jun 18 '18 at 18:26
Can't do that. Every loop you overwrite your "var" with the var declaration. — Daniel, Jun 18 '18 at 18:26
You can't do like 'var b + n' instead, you can try ' b[n]'. You can't make a variable name with + operator. — c-an, Jun 18 '18 at 18:31

Try to use the Array

var b = new Array();
for (var n = 0;  n < 10; n++) 
{  
    b[n] = document.getElementById("b" + n);               
}
