Q
What will be the output of the following JavaScript code? Code: let count = 0; do { console.log(count); count++; } while (count < 3);

Answer & Solution

Answer: Option A
Solution:
The code snippet uses a do...while loop to execute a block of code at least once and then repeatedly as long as the condition count < 3 is true. It starts with count being 0 and prints the value of count to the console in each iteration, then increments count by 1. This process continues until count is no longer less than 3, at which point the loop stops. Therefore, the output will be: 0 1 2
