Q

What does the following JavaScript code snippet do? Code: let num = 5; while (num > 0) { console.log(num); num--; }

A). Declares a variable and assigns a value to it B). Executes a block of code repeatedly until a condition becomes false C). Calculates the sum of numbers from 1 to 5 D). Checks if a number is positive or negative

Answer & Solution

Answer: Option B

Solution:

The code snippet uses a while loop to execute a block of code repeatedly until the condition num > 0 becomes false. It starts with num being 5 and prints the value of num to the console in each iteration, then decrements num by 1. This process continues until num becomes 0, at which point the loop stops. Therefore, the output will be: 5 4 3 2 1
