What is the output of the following code?var arr = [1, 2, 3, 4, 5];arr...

Explanation:

forEach method:
- The `forEach` method is used to execute a provided function once for each array element.
- In this code snippet, the `forEach` method is called on the `arr` array.

Function inside forEach:
- The function passed to `forEach` takes an `element` parameter, which represents each element of the array.
- Inside the function, each element is multiplied by 2 using `element * 2`.
- The result of the multiplication is then logged to the console using `console.log`.

Output:
- The output of the code will be the result of multiplying each element of the array by 2.
- So, the output will be: 2, 4, 6, 8, 10.

Therefore, the correct answer is option 'A' - 2, 4, 6, 8, 10.
