Why does it show alert box 2 times?

Here is my code. 

function quiz() {
a = parseInt(prompt("Type the lowest possible value"));
b = parseInt(prompt("Type the highest possible value"));
result = Math.floor(Math.random() * (b - a + 1)) + a; 
  return result;

}
quiz();

document.write("Your number is " + quiz());

function quiz() {
a = parseInt(prompt("Type the lowest possible value"));
b = parseInt(prompt("Type the highest possible value"));
result = Math.floor(Math.random() * (b - a + 1)) + a; 
  return result;

}
quiz();  //you don't need to call quiz() here...you are just calling it and not doing anything with it

document.write("Your number is " + quiz()); //since you are calling quiz() here for use in your document.write statement

You have 2 prompt statements.

a = parseInt(prompt("Type the lowest possible value"));
b = parseInt(prompt("Type the highest possible value"));
