Answer: The code provided has a few issues that need to be addressed for it to function correctly. Firstly, the foreach method should be written as forEach with a capital "E." Secondly, the sum assignment in the sumarray function should be an addition operation (sum += value) instead of a simple assignment (sum = value).
Here's the corrected code:
javascript
var sum = 0;
var x = [1, 3, 7, 11];
x.forEach(sumarray);
function sumarray(value) {
sum += value;
}
console.log(sum);
The output of this code will be:
22
The forEach method iterates over each element in the array x, and the sumarray function adds each value to the sum variable. In this case, the sum of the array elements [1, 3, 7, 11] is 22, which is the final output.
