How to split a comma separated string and process in a loop using JavaScript?

To split a comma separated string and process in a loop using JavaScript, we use the split method and a for-of loop.

For instance, we write

const str = "Hello, World, etc";
const myArray = str.split(",");

for (const a of myArray) {
  console.log(a);
}

to call str.split with ',' to return an array with the strings between the commas.

And then we use a for-of loop to loop through the myArray entries.

We get the entry being looped through from a.
