the array length

For some reasons I don't want to specify the lenght of an array, but I need later to use that value. Is it possible?

var a = new Array()
a[0] =
a[1] =
a[2] =

I need something like a.lenght to use this value in an incremental loop...

for(i=0;i++;i<a.lenght)...

}
should do the trick

it should be

for(i=0;i<a.length;i++)

not

for(i=0;i++;i<a.length)

thank you
