Lottery DataBase Analysis - 07 (_.isObject & passing an object)
From Here on Out, I will no longer be pasting this table into the web
page or creating the JSON object dynamically.
THIS
SPUR explains how the table got transformed into JSON and I
will simply
utilize the transformed JSON data from here on out. Doing
this will save the need to
load the TableToJSON library. And until it is needed for
graphical
output (I expect to try my hand at FLOT with requires JQuery),
the JQuery library will no longer be required either.
(Of course, one of the reasons for doing this is an error I
was gettign from using multiple libraries at once.)

Which I have saved as a JSON Object. (The above is nothing
more than HTML text and is not linked to any JavaScript.)
//Array to pass to Next Function (to
determine Expected Return Per Prize Level)
var tempArray1 = _.zip(prizeAmounts,
numWin);
document.getElementById('outputOne').innerHTML = _.map(tempArray1,
function(n){return ' ' + n;});
outputOne =
3250000,17, 5000,34, 1000,102, 500,3400, 100,63240, 40,116620, 20,765000, 15,1020000, 10,2040000, 5,3570000, 5,4080000
// Error is An Object
var tempArray2 = _.map(tempArray1, function(a){return _.isObject(a);});
document.getElementById('outputTwo').innerHTML = _.map(tempArray2, function(n){return ' ' + n;});
outputTwo =
true, true, true, true, true, true, true, true, true, true, true
var tempArray3 = _.map(tempArray1, function(a,b){return a * b;});
document.getElementById('outputTwo').innerHTML = _.map(tempArray3, function(n){return ' ' + n;});
tputThree =
NaN, NaN, NaN, NaN, NaN, NaN, NaN, NaN, NaN, NaN, NaN
var tempArray4 = _.map(tempArray1, function(a){
return a[0] * a[1];
});
document.getElementById('outputTwo').innerHTML = _.map(tempArray4, function(n){return ' ' + n;});
outputFour =
55250000, 170000, 102000, 1700000, 6324000, 4664800, 15300000, 15300000, 20400000, 17850000, 20400000
Using the original JSON lotteryData, we can pull data directly (so don't ask me why I was plucking and zipping before.
var tempArray5 = _.map(lotteryData, function(a){
return a.Prizes;
//Total # of Winners
});
document.getElementById('outputTwo').innerHTML = _.map(tempArray5, function(n){return ' ' + n;});
outputFive =
$3,250,000, $5,000, $1,000, $500, $100, $40, $20, $15, $10, $5, Ticket
This last indates that:
- There are easier ways to pull data from a JSON object.
- My life will be easier in the long run if I preformat the JSON object (remove strings, rename keys, maybe more).
So, time to reformat the Spur again.

Please Note: I am an idiot. No seriously. The odds
of my
gambling
odds calculations being correct are likely on par with my odds of ever
winning. You have been warned.
