Question

Besides iterating, what can Array.length be used for?

A. Creating an array.
B. Adding elements to an array.
C. Removing elements from an array.

Answer 1

The Array.length property can be used for creating an array by setting the size or removing elements by reducing the length. It is not typically used for adding elements to an array.

Step-by-step explanation:

Besides iterating over an array, the Array.length property in Javascript has other uses such as:

• Creating an array: You can use Array.length to set the size of a new array.
• Removing elements: It is possible to remove elements from an array by setting the Array.length property to a value less than the current length.

However, it is not typically used for adding elements to an array, as this is commonly achieved through methods like push() or splice().
