# My result for displaying a random number between two inputs.

Hi. I completed Jim's Introduction to Programming course before this one, so I kind of went ahead and used some conditional stuff and a loop :) My code seems to work but I feel like I have written a little too much and repeated myself a little. Could I ask for some suggestions for improvement?

Thanks & cheers!

```/***** RANDOM NUMBER GENERATOR *****/

var input1 = parseInt(prompt('Give me a number:'));
var input2 = parseInt(prompt('Nice! Now give me another number:'));

// Make sure two inputs are different
while(input1 == input2) {
input2 = parseInt(prompt('Please give me a different number:'));
}

// Display inputs
console.log('Input 1: ' + input1);
console.log('Input 2: ' + input2);

// Make sure the difference of the two inputs is positive.
var diff = input1 - input2;
console.log('Difference of inputs: ' + diff);
if(diff < 0) {
diff *= -1;
}

// Filler
alert('Thank you! Now I\'ll give you a number back, generated between the ones you provided.');

// Random number between 1 and the absolute value of the difference of two inputs.
var result = Math.floor(Math.random() * diff) + 1;
console.log('Result before: ' + result);

// Find and add the smaller input to the result so that the result becomes between the two inputs, including both of them.
if(input1 < input2){
result += Math.floor(input1);
} else {
result += Math.floor(input2);
}

console.log('Result after: ' + result);

// Display result
```

OK, I just found a glitch on line 27. Before the correction, it does not include the smaller number in the result interval, now it does.

```// Random number between 0 and the absolute value of the difference of two inputs.
var result = Math.floor(Math.random() * (diff + 1));
``` OK. I'll give it a shot. I added some extra stuff as well such as verifying that numbers entered are numbers and throwing errors.

```/*----------------
THE SETUP
----------------*/
// vars
var minNumber,
maxNumber,
randomNum,
requestMinNumber = "Give me a number:",
minNumberConfirmation = "Nice!",
requestMaxNumber = "Now give me another number that is bigger than the first number:",
maxNumberConfirmation = "Thank you! Now I'll give you a random integer between the numbers that you provided.";

// prompt user for a valid integer
var getInt = function(question){
var theNumber;
do{
theNumber = parseInt( prompt(question) );
}while( isNaN(theNumber) );
return theNumber;
};

// generate a random number between 2 values
var getRandomIntegerBetween = function( minLimit, maxLimit ){
if( isNaN(minLimit) || isNaN(maxLimit) ){
throw new Error("Error: getRandomIntegerBetween(num1, num2) requires 2 numeric values");
}
return Math.floor( Math.random() * ( maxLimit - minLimit + 1 ))  + minLimit;
};

/*----------------
START THE WORK
----------------*/
// get the low number
minNumber = getInt( requestMinNumber );

// confirm reciept of the first number

// get the high number
do{
maxNumber = getInt( requestMaxNumber );
}while( minNumber >= maxNumber );

// confirm reciept of the second number
