getting array value in console

I have an array (tot) with arrays in it. I need to check each entry in (tot) for a value , which is done at console by typing AA[3] , however, when I execute it from a script, AA[3] would NOT return any value!

here is my script:

tot=["AA","AB","AC"];
AA=["1","2","3","4","5","6","7"];
AB=["1","2","3","4","5","6","7"];
AC=["1","2","3","4","5","6","7"];

for (let i = 0; i < tot.length; i++)  
{
tot[i]+'[2]';
}

Solution

  • I have an array (tot) with arrays in it

    Actually that's inaccurate. You have an array with string values inside that are not arrays. The values of the strings you have in your array match the names of some arrays. Instead of this you might want to use an object of arrays, like:

    let AA=["1","2","3","4","5","6","7"];
let AB=["1","2","3","4","5","6","7"];
let AC=["1","2","3","4","5","6","7"];
let tot={AA,AB,AC};
let index = 5;

for (let key in tot) {
    console.log(`${key}[${index}]: ${tot[key][index]}`);
}
