Q
What will be the output of the following JavaScript code? Code: let i = 1; do { console.log(i); i++; } while (i < 3);

Answer & Solution

Answer: Option A
Solution:
The code snippet uses a do...while loop to print numbers from 1 to 2. It starts with i being 1 and prints the value of i to the console in each iteration, then increments i by 1. This process continues until i is no longer less than 3, at which point the loop stops. Therefore, the output will be: 1 2
