Q
What will be the output of the following JavaScript code? Code: let x = 10; while (x > 0) { console.log(x); x -= 2; }

Answer & Solution

Answer: Option A
Solution:
The code snippet uses a while loop to print even numbers from 10 to 0. It starts with x being 10 and prints the value of x to the console in each iteration, then decrements x by 2. This process continues until x becomes 0, at which point the loop stops. Therefore, the output will be: 10 8 6 4 2 0
