What will be the output of the following code?let arr = [1, 2, 3, 4, 5...
Code Explanation:
The given code declares an array `arr` with values `[1, 2, 3, 4, 5]`. It then uses a `for...of` loop to iterate over each element in the array. Inside the loop, it checks if the current element is equal to 3. If it is, the loop is terminated using the `break` statement. If the element is not equal to 3, it is logged to the console using `console.log`.
Code Execution:
1. The loop starts with the first element of the array, which is 1.
2. Since 1 is not equal to 3, it is logged to the console.
3. The loop moves to the next element, which is 2.
4. Again, 2 is not equal to 3, so it is logged to the console.
5. The loop moves to the next element, which is 3.
6. As 3 is equal to 3, the `break` statement is executed, terminating the loop.
7. Hence, the loop does not continue to the remaining elements of the array (4 and 5).
8. The output of the code execution will be:
```
1
2
3
```
Conclusion:
The given code will output the numbers 1, 2, and 3. The loop terminates when it encounters the element 3, so the remaining elements (4 and 5) are not logged to the console. Therefore, the correct answer is option A: 1 2 3 4 5.
