Looping Arrays In JavaScript

There are several ways to loop through an array in JavaScript, including:

1. The for loop: This is the most traditional way to loop through an array, and it allows you to access both the index and the value of each element in the array.

var arr = [1, 2, 3, 4, 5];
for (var i = 0; i < arr.length; i++) {
    console.log(arr[i]);
}

2. The forEach() method: This method allows you to iterate through an array and execute a callback function for each element in the array.

var arr = [1, 2, 3, 4, 5];
arr.forEach(function(value) {
    console.log(value);
});

3. The for...of loop: This looping construct allows you to iterate over the values of an array, without having to reference the index.

const arr = [1, 2, 3, 4, 5];
for (const value of arr) {
    console.log(value);
}

4. The for...in loop: This looping construct allows you to iterate over the properties of an object. It can also be used to iterate over the indexes of an array.

const arr = [1, 2, 3, 4, 5];
for (const index in arr) {
    console.log(arr[index]);
}

Conclusion

You can use any of the above method based on your requirement.
