## Why Use `[].forEach.call()` to Iterate Over Node Lists in JavaScript?

Understanding the Behavior of [].forEach.call() in JavaScript

[][] is an empty array in JavaScript that grants access to array prototypes like .forEach. This mechanism is often employed to iterate over node lists because it offers a convenient way to execute a function on each element in a node list.

The .call() method is a function prototype that allows you to replace the 'this' keyword within a function with a specified object. In the context of [].forEach.call(), the empty array is assigned as the caller object (this), while the node list is passed as the first argument to the .forEach() method.

This technique simplifies the process of looping over a node list by providing direct access to array-like properties and methods. The function passed to .forEach() receives three arguments:

1. The current node element
2. The index of the element
3. The node list itself

For example, the following code snippet uses [].forEach.call() to iterate over all 'a' tags on a web page:

``
[].forEach.call(document.querySelectorAll('a'), function(el) {
// Do something with each 'a' tag
});
``

While .forEach() is a convenient way to iterate over node lists, it is worth noting that hackish and unsightly solutions, such as using [].forEach.call(), can clutter your codebase. It is recommended to stick to inline looping or use clean helper methods and libraries that provide this functionality in a more readable and maintainable manner.

ES6 introduces more straightforward options, such as the Rest and Spread operators, which make it easier to convert between arrays and array-like objects, eliminating the need for hackish approaches.
