can you track index with forEach javascript code example

Example 1: javascript enumerate with index

const iterable = [...];
for (const [index, elem] in iterable.entries()) {
  f(index, elem);
}

// or
iterable.forEach((elem, index) => {
  f(index, elem);
});

Example 2: forEach index

const array1 = ['a', 'b', 'c'];

array1.forEach((element, index) => console.log(element, index));
