Q
What will be the output of the following JavaScript code? Code: let nums = [1, 2, 3, 4, 5]; for (let n of nums) { if (n % 2 === 0) { console.log(n); } }

Answer & Solution

Answer: Option B
Solution:
The code snippet uses a for...of loop to iterate through each element n in the array nums. Inside the loop, it checks if n is even (divisible by 2), and if so, it prints n to the console. Therefore, the output will be: 2 4
