myArray
with the given data:["Heine", 25, "Bob", 16]
. - Remove the last element,

, from the array. - Add a new element with the value

using indexing. - Print the updated array to the console.
let ___ = ["Heine", 25, "Bob", 16]; myArray.___(); myArray.___(21); myArray[___] = 27; console.log(___);
The output should be :
- Use the
pop()
method to remove an element from the end of an array. - Use the
push()
method to add an element to the end of an array. - Access the second element in the array using the index
1
. - To log the array data to the console, use the
console.log()
with the array name.
let myArray = ["Heine", 25, "Bob", 16]; // Step 1 myArray.pop(); // Step 2 myArray.push(21); // Step 3 myArray[1] = 27; // Step 4 console.log(myArray); // Step 5
