We then use slice() to get the last element of the array by passing a negative index (-1) as the second argument to slice().

In this example, we define an array of numbers called numbers. Here is an example of how you might use slice() to get the last element of an array: // define an array of numbers This will return a new array with the elements starting from the end of the original array, rather than from the beginning. To get the last element of an array using the slice() method in JavaScript, you can pass a negative index as the second argument to slice(). It also modifies the numbers array, so the length of the array is now 4 and the index of the last element is now 3. This method returns the value 5, which is the last element of the array. In this example, we use pop() to remove and return the last element of the numbers array.

Here is the same example using pop(): // define an array of numbers This method modifies the original array, so keep in mind that it will change the length of the array and shift the index of all other elements. pop()Īlternatively, you can use the pop() method to remove and return the last element of an array.

We use the notation to access the element at this index, which returns the last element of the array with the value 5. We then use the length property to get the total number of elements in the array, and subtract 1 from this value to get the index of the last element.

Here is an example of how you might use the length property and the notation to get the last element of an array: // define an array of numbers The length property returns the number of elements in an array, and the notation allows you to access an element at a specific index in the array. To get the last element of an array using JavaScript, you can use the length property and the square bracket notation.
