JavaScript's Array filter method is a built-in function that creates a new array with all elements that pass a certain test provided as a callback function. The filter method iterates over each element of the original array, invoking the callback function with the element, index, and array as arguments. If the callback function returns true, the element is added to the new filtered array, otherwise, it is excluded. The filter method does not modify the original array, it returns a new array containing the filtered elements. The JavaScript Array filter method is a powerful tool for selecting, transforming and cleaning data in JavaScript arrays.
