Fill textfields with a for loop

Hello.
If i have ten textfields named field_1 to field_10 and i want to fill them with a for loop, how do i refer to each instance name?
Obviously the problem lays in “field_i.text” in the following code:

for (var i=0; i<10 i++) {

field_i.text= i;
			
}

I just dont know how to refer to the instance name correctly using the i.
I bet its simple but its hard to find, any guru here can help me out?

Regards
