JavaScript Mastery from Zero to Hero - Prepare for Coding Interviews - Example 2 - What Is Splice in JavaScript

This video tutorial covers the use of the splice method in JavaScript to manipulate arrays. It explains how to use splice to remove elements from an array and store them in a new array. The tutorial includes examples and exercises to help learners understand the concept. The video concludes with a preview of the next lesson, which involves solving a puzzle using splice.

What is the primary purpose of using the splice method as introduced in the lesson?

• To create a new array with removed items

• To find the length of an array

• To add new elements to an array

• To sort the elements of an array

In the example provided, which elements are extracted from the array using the splice method?

• 1 and 2

• 1 and 4

• 3 and 4

• 2 and 3

What happens to the original array after using the splice method in the example?

• It loses the extracted elements

• It becomes empty

• It doubles in size

• It remains unchanged

Which of the following is NOT a characteristic of the splice method as discussed?

• It can remove elements from an array

• It can add elements to an array

• It can create a new array with removed elements

• It sorts the array in ascending order

What is the next topic hinted at the end of the lesson involving the splice method?

• Solving a puzzle using splice

• Sorting arrays

• Adding elements to arrays

• Finding the maximum value in an array
