如何将这个对象数组映射到一个新的对象数组,其中对象的id是键,它的值是对象?
var players = [{id: 2, score: 5}, {id: 3, score: 10}]
var mapped = _.map(players, function(x) { return {x.id: x}})
// desired output = [{2: {id: 2, score: 4}, {3: {id: 3, score: 10}} ]
尝试上述Uncaught SyntaxError: Unexpected token .(…)

首先,在你的JS小提琴中,你没有包括underscore,但这会有效:
var mapped = _.map(players, function(player) {
var playerObj = {};
playerObj[player.id] = player;
return playerObj;
})

如果您对使用ES6功能感到满意,那么您可以使用箭头函数,该函数使用计算属性名称:
form(action="/user/create", method="post")
label(for="name") Name
input(type="text", id="name", name="name", value="", autofocus)
label(for="surname") Surname
input(type="text", id="surname", name="surname", value="")
