I've gone through the Lynda courses on JSON and really searched around to solve this bug; however, I guess my question is too specific and I need an example.

From what I've gathered from searching and videos I think the code below is close. The issue must be that this inst just a value in an array but another object?
for (i = 0; i <= body.games.length; i++){
for (var key in body.games[i]) {
console.log("Game " + (i +1));
console.log(body.games[i][key].away.odds.acesport);
}
}
Your post doesn't contain a question. I will assume the questions "How to access an object in an array?" and "Why does my code not work?".
Maybe this example will clarify it for you.
for (var i = 0; i <= body.games.length; i++) {
var game = body.games[i];
console.log("Game number " + (i + 1));
console.log(game.away.odds.acesport);
for (var key in game) {
// This will print the strings "away", "home", "time" and "status",
// but not the values game[key] which are "object", "object",
// "7:05 PM EST" and "Final".
console.log("Game property: " + key);
}
}
You are trying to access body.games[i].away.away.odds.acesport
, this wont work. You should try some approaches:
Just get the values of the 2 keys you know have the properties you want.
for (i = 0; i <= body.games.length - 1; i++){
console.log("Game " + (i +1));
console.log(body.games[i].away.odds.acesport);
console.log(body.games[i].home.odds.acesport);
}
Check if the property odds and acesport exists. This is more scalable.
for (i = 0; i <= body.games.length - 1; i++) {
console.log("Game " + (i +1));
for (var key in body.games[i]) {
var acesport = body.games[i][key].odds && body.games[i][key].odds.acesport;
if (acesport) console.log(acesport);
}
}
Now, if you want to try a little cleaner:
body.games.forEach(function(game, index) {
console.log("Game " + index + 1);
Object.keys(game).forEach(function (prop) {
var acesport = game[prop].odds && game[prop].odds.acesport;
if (acesport) console.log(acesport);
});
});
Or cleaner yet (if you can use string template and arrow functions):
body.games.forEach((game, index) => {
console.log(`Game ${index + 1}`);
Object.keys(game).forEach((prop) => {
var acesport = game[prop].odds && game[prop].odds.acesport;
if (acesport) console.log(acesport);
});
});
