Quiz Explanation

This JavaScript code defines two variables a and b with values 5 and 10 respectively. Then, it declares a function named multiply. Inside the function, a local variable a is declared with a value of 3. It then multiplies this local a with the global variable b and assigns the result to a local variable c. Finally, it logs the value of c to the console.

When multiply() is called, it calculates 3 * 10 and logs 30 to the console.

After that, it logs the value of the global variable a (which is 5) to the console outside the function.

So, the output of this code will be:

30
5
