forEach loop in JavaScript

The forEach loop is a built-in method in JavaScript that allows you to iterate over elements in an array or any other iterable object. It provides a concise and expressive way to perform an operation on each element without the need for a traditional for loop. In this response, we'll explore the forEach loop in detail, covering its syntax, behavior, and common use cases.

Syntax of forEach loop in JavaScript:

array.forEach(callback(currentValue, index, array) {
    // code
});

Here, array represents the array or iterable object you want to iterate over. The callback function is a function that will be executed for each element in the array. It takes three parameters: currentValue, which represents the current element being processed, index, which represents the index of the current element, and array, which represents the array being traversed. The code block within the curly braces will be executed for each element.
