Q
What does the following JavaScript code snippet do? Code: let x = 5; while (x > 0) { console.log(x); x -= 1; }

Answer & Solution

Answer: Option C
Solution:
The code snippet uses a while loop to print numbers from 5 to 0. It starts with x being 5 and prints the value of x to the console in each iteration, then decrements x by 1. This process continues until x becomes 0, at which point the loop stops. Therefore, the output will be: 5 4 3 2 1 0
