In this article, we’ll look at how to dynamically creating variables in for loops with JavaScript.

How to dynamically creating variables in for loops with JavaScript?

To dynamically creating variables in for loops with JavaScript, we use an array.

For instance, we write

const createVariables = () => {
  const accounts = [];
  for (let i = 0; i <= 20; ++i) {
    accounts[i] = "whatever";
  }
  return accounts;
};

to define the createVariables function.

In it, we loop from i between 0 to 20.

And we use i as the index of the entry we want to put into accounts.
