Retrieve elements within the array ranging from index 1 to 5 using Javascript

How can I log items from index 1 to 5 in the current array by using a loop?

let cars = ["AUDI","BMW","LEXUS","VOLKSWAGEN","FERRARY","PORSCHE"]

for (let i = 0; i < cars.length; i++) {
    if (i >= 1 && i <= 5) {
        console.log("The current index is: " + i);
        console.log("The current element is: " + cars[i]);
        console.log("\n");
    }
}

Utilizing a for loop, you have the ability to set the initial condition and the condition that will end the loop.

for ([initialExpression]; [condition]; [incrementExpression])
 statement

let fruits = ["apple", "banana", "orange", "mango", "kiwi", "pineapple"]

const selectedFruits = [];
for (let j=0; j<5; j++) {
        selectedFruits.push(fruits[j]);
}

console.log(selectedFruits);

To accomplish this task using a loop iterating from indexes 1 to 5 (inclusive):

let cars = ["AUDI","BMW","LEXUS","VOLKSWAGEN","FERRARY","PORSCHE"]

const filteredCars = [];
for (let i=1; i<=5; i++) {
        filteredCars.push(cars[i]);
}

console.log(filteredCars);

An alternative approach without a loop is to utilize filter() or slice(). Here's an example using filter():

let cars = ["AUDI","BMW","LEXUS","VOLKSWAGEN","FERRARY","PORSCHE"]

const filteredCars=cars.filter((item, i) => i>=1 && i<=5);

console.log(filteredCars);

If you want to achieve this using the forEach method:

let cars = ["AUDI","BMW","LEXUS","VOLKSWAGEN","FERRARY","PORSCHE"];

function repeatElement(element, index) {
  console.log(`The current index is: ${index}`);
  console.log(`The current element is: ${element}`);
}

cars.forEach(repeatElement);
