Q

What does the following JavaScript code snippet do? Code: let a = 10; let b = 20; let temp = a; a = b; b = temp; console.log(a, b);

A). A) Swaps the values of a and b B). B) Adds a and b C). C) Checks if a is equal to b D). D) Multiplies a and b

Answer & Solution

Answer: Option A

Solution:

The code snippet swaps the values of variables a and b. It uses a temporary variable temp to hold the value of a, then assigns b to a, and finally assigns the value of temp (which was the original value of a) to b. So, after execution, a will have the value of 20 and b will have the value of 10, and the output will be 20 10.
