Вивчайте for...of and forEach | Building Conditions and Repetition

Imagine you have a grocery list and you want to check every single item to make sure nothing is missing. You would start at the top of the list and look at each item one by one until you reach the end. In programming, when you want to process every item in a list—like an array of fruits—JavaScript gives you two handy tools: the for...of loop and the forEach method. Both help you visit each element in an array, but they work in slightly different ways.

const fruits = ["apple", "banana", "cherry"];

for (const fruit of fruits) {
  console.log("I need to buy " + fruit);
}


              12345
            
const fruits = ["apple", "banana", "cherry"];

fruits.forEach(function(fruit) {
  console.log("I need to buy " + fruit);
});
