How to loop through an array containing objects and access their properties with JavaScript?

Spread the love

To loop through an array containing objects and access their properties with JavaScript, we use the forEach method.

For instance, we write

yourArray.forEach((arrayItem) => {
  const x = arrayItem.prop + 2;
  console.log(x);
});

to call forEach with a callback that gets the prop property value from the arrayItem being looped through.

And then we add 2 to it assign the sum to x.
