我看到这个标题有几个问题，但是似乎没有一个可以正确回答我的问题。我正在尝试通过json对象进行映射，并将每个属性值插入变量中。
我已经尝试了几乎所有我能找到的其他示例，它们要么抛出了语法错误，要么没有完成我试图做的事情
更新： 为了提供更多背景信息，我使用了一个名为glicko2 https://www.npmjs.com/package/glicko2的npm软件包。 makePlayer（），rankings.updateRatings（）、. getRating（）、. getRd（）、. getVol（）都是内置在npm包中的原型方法。 这是完整的文档。如果将其放在js文件中并安装npm软件包，它将为您运行所有计算。本质上，我想做的是编写一个函数，在其中可以将任何播放器数据输入到该函数中，而不必像示例中那样对其进行硬编码并仍然获得计算结果：
var settings = {
// tau : "Reasonable choices are between 0.3 and 1.2, though the system should
// be tested to decide which value results in greatest predictive accuracy."
tau : 0.5,
// rating : default rating
rating : 1500,
//rd : Default rating deviation
// small number = good confidence on the rating accuracy
rd : 200,
//vol : Default volatility (expected fluctation on the player rating)
vol : 0.06
};
var ranking = new glicko2.Glicko2(settings);
// Create players
var Ryan = ranking.makePlayer();
var Bob = ranking.makePlayer(1400, 30, 0.06);
var John = ranking.makePlayer(1550, 100, 0.06);
var Mary = ranking.makePlayer(1700, 300, 0.06);
//We can then enter results, calculate the new ratings...
var matches = [];
matches.push([Ryan, Bob, 1]); //Ryan won over Bob
matches.push([Ryan, John, 0]); //Ryan lost against John
matches.push([Ryan, Mary, 0.5]); //A draw between Ryan and Mary
ranking.updateRatings(matches);
//... and get these new ratings.
console.log("Ryan new rating: " + Ryan.getRating());
console.log("Ryan new rating deviation: " + Ryan.getRd());
console.log("Ryan new volatility: " + Ryan.getVol());

// heres what I have so far. What I want to happen is have playerName[0].name
// be the variable name and set that equal to the rest of the equation. That
// way I can plug in the variable player0 into the matches array to run my
// calculations. The problem I am having is when the code is getting to the
// const matches array it is saying that player0 is undefined.
// heres what I do know:
// allPlayerStats is a properly formatted json object.
// I have console logged every bracket/dot notation property separately to know
// that all of them are written in proper syntax.

// var player2 = ranking.makePlayer(1750, 300, 0.06);
