我有一个对象数组（带有keys: name, quoteNumber），我想找到最接近quoteNumber的小于给定数字的对象，然后检索该对象的名称，我已经考虑使用 for 循环来删除较大的值，并获得最大值从其余的，但考虑到数据集有多大，它可能不是最好的选择。这是任何其他更有效的算法吗？谢谢！

const givenNum = 45
var array = [ 

    { name: "Sally",
      quoteNumber: 35},
    { name: "Jane",
      quoteNumber: 20},
    { name: "Edwin",
      quoteNumber: 55},
    { name: "Carrie",
      quoteNumber: 47}];
