❌ B ✔️ Explanation: The Set object only stores unique values. In this case, the array [1, 2, 2] contains a duplicate 2. When you create a set using new Set([1, 2, 2]), it will only store unique values, so the set will be {1, 2}. The size of the set is 2 because it has two unique elements: 1 and 2. So, the correct answer is B) 2.

❌ B ✔️ Explanation: The shift() method removes the first element from an array and returns it. Initially, the array arr is [1, 2, 3]. After calling arr.shift(), the first element (1) is removed, and arr becomes [2, 3]. console.log(arr) will output [2, 3]. So, the correct answer is B) [2, 3].

B) To executive the block conditionally

1. Initialization: let x = 0; initializes x to 0. 2. While loop condition: (x++ < 5, x < 3) is using the comma operator, which evaluates both expressions but only returns the value of the second one (x < 3). x++ < 5: This means the value of x is checked and then incremented by 1. x < 3: This is the condition that controls the loop. Iteration breakdown: 1. First iteration: Initial value of x is 0. x++ means x is compared as 0, then incremented to 1. The condition x < 3 is checked, which is true (1 < 3), so the loop runs. console.log(x) prints 1. 2. Second iteration: Now, x is 1. x++ means x is compared as 1, then incremented to 2. The condition x < 3 is checked, which is true (2 < 3), so the loop runs. console.log(x) prints 2. 3. Third iteration: Now, x is 2. x++ means x is compared as 2, then incremented to 3. The condition x < 3 is checked, which is false (3 < 3), so the loop stops. Output: The values printed by console.log(x) are 1 and 2. Thus, the correct output is A) 1, 2.

❌ B ✔️ Explanation 👇 1.arr is declared as an empty array []. 2. func is a function that returns the arr when called. 3. func() is called, so it returns arr, which is an empty array. 4. typeof is used to check the type of the value returned by func(). Since func() returns an array, and in JavaScript, arrays are considered objects, the result of typeof func() will be "object". The output will be object. So, the correct option is: B) object.

@@SortedCoding damn, thank you.

@@swuppy-real-170 C ❌ B ✔️ The pop() method removes the last element of the array and returns it. In the array arr = [1, 2, 3, null], the last element is null. When arr.pop() is executed, null is removed, and it is returned by the pop() method. So, the value of removed will be null. Therefore, the correct output will still be null, and the correct option remains B) null.
