What are some examples of for loops in JavaScript?

What are some examples of for loops in JavaScript?

Sure! A for loop in JavaScript is used to execute a block of code a certain number of times. Here's a basic example:

for (let i = 0; i < 5; i++) {
    console.log(i);
}

This will print numbers 0 to 4 in the console.

Can you show me a for loop that iterates over an array?

Absolutely! Here's an example of a for loop that iterates over an array:

const fruits = ['apple', 'banana', 'cherry'];
for (let i = 0; i < fruits.length; i++) {
    console.log(fruits[i]);
}

This will print each fruit in the array.

What about a for loop with a condition?

Sure! You can add a condition inside the loop. For example:

for (let i = 0; i < 10; i++) {
    if (i % 2 === 0) {
        console.log(i + ' is even');
    }
}

This will print only the even numbers from 0 to 9.

Can you explain the difference between for loop and forEach?

Certainly! A for loop gives you more control over the iteration process, while forEach is a method that executes a provided function once for each array element. Here's a quick comparison:

// Using for loop
for (let i = 0; i < array.length; i++) {
    console.log(array[i]);
}

// Using forEach
array.forEach(item => console.log(item));
