Counter variable i inside variable name

Question

Is it possible to put the counter variable value inside a variable?

I just want to have in the first loop testData_0_name, in the second testData_1_name etc. Those are my parameters in my records

for(var i = 0; i < record.length;i++)
{
    record[i].testData_ **here I want to have  "i"**_name ....
}

I don't really want to use any global scopes or something with [window].

since i is declared inside for loop, it will only affect in that scope — Akhil Aravind, May 25 '18 at 09:38
I don't think you can rename a variable in Java with some iterator or other variables. Maybe someone will prove me wrong. — Lutzi, May 25 '18 at 09:38
I'm afraid I have no idea what you are trying to say and do. What does "iterator inside a variable" mean for you? What are you actually intending to do here? — OH GOD SPIDERS, May 25 '18 at 09:39
I know, i just want to have in the first loop > testData_0_name, in the second testData_1_name etc. Those are my parameters in my records. — randomcat, May 25 '18 at 09:39

var records = [{'testData_0_name': 0}, {'testData_1_name': 1}, {'testData_2_name': 2}, {'testData_3_name': 3}];

for(var i = 0; i < records.length;i++)
{
    console.log(records[i]['testData_'+i+'_name'])
}

You can use bracket notation to access object properties and we can also customize the string in bracket notation like other strings.
