我是 JavaScript 新手。在没有 for 循环的情况下从字典列表中提取特定键的值的最佳方法是什么?例如:
var = [{ name: "Rusty", type: "human", legs: 2, head: 1 },
{ name: "Alex", type: "human", legs: 2, head: 1 },
{ name: "Lassie", type: "dog", legs: 4, head: 1 },
{ name: "Spot", type: "dog", legs: 4, head: 1 },
{ name: "Polly", type: "bird", legs: 2, head: 1 },
{ name: "Fiona", type: "plant", legs: 0, head: 1 }]
