How to loop through an array without using array size with Node?

Spread the love

To loop through an array without using array size with Node, we use the forEach method.

For instance, we write

const myArray = ["1", "2", 3, 4];

myArray.forEach((value) => {
  console.log(value);
});

to call forEach with a callback that gets the entry in myArray being looped through.

We get the value being looped through from value.
