Question

After the following code runs, what will be the value of result? var x = 30; function get () { return x; } function set (value) { x = value; } set(10); var result = get(20);

Answer 1

Answer:

Null

Explanation:

It entirely depends on the language you are using to implement this.

But generally by the rule of scope, "result" will return null since get() was not defined to accept any argument, and it neither know the global "x" not defined it's own x in the function.
