AWS, JavaScript, React - Deploy Web Apps on the Cloud - JavaScript Splicing an Array

The video tutorial explains the splice method for arrays, which allows adding new elements at a specified position and optionally removing existing elements. An example is provided where two fruits, lemon and banana, are added after the second element, orange, in an array. The tutorial details the use of index and removal parameters in the splice method and verifies the output to ensure correctness.

What does the splice method allow you to do with an array?

• Sort the array in ascending order

• Add elements at a specific position and remove elements

• Find the maximum value in the array

• Reverse the order of elements in the array

In the example, where are lemon and banana added in the array?

• After the first element

• At the end of the array

• After the second element

• At the beginning of the array

What does the first parameter of the splice method represent?

• The type of elements to add

• The total length of the array

• The index at which to start adding new elements

• The number of elements to remove

What does the second parameter of the splice method indicate in the example?

• The index of the last element

• The number of elements to add

• The number of elements to remove

• The type of elements to remove

What confirms that the splice method was executed correctly in the example?

• The array is sorted alphabetically

• Lemon and banana appear after orange

• The array is reversed

• The array length is reduced
