如果您的环境支持Object.assign，那么您可以像这样简洁地进行操作
const arrObj = [{a: 1, b: 2}, {c: 3, d: 4}, {e: 5, f: 6}];
console.log(arrObj.reduce(function(result, current) {
return Object.assign(result, current);
}, {}));
// If you prefer arrow functions, you can make it a one-liner ;-)
console.log(arrObj.reduce(((r, c) => Object.assign(r, c)), {}));
// Thanks Spen from the comments. You can use the spread operator with assign
console.log(Object.assign({}, ...arrObj));
ES5解决方案：
您可以使用Array.prototype.reduce这样的
var resultObject = arrObj.reduce(function(result, currentObject) {
for(var key in currentObject) {
if (currentObject.hasOwnProperty(key)) {
result[key] = currentObject[key];
}
}
return result;
}, {});
console.log(resultObject);
# { a: 1, b: 2, c: 3, d: 4, e: 5, f: 6 }
此解决方案仅将的所有键及其值收集在中的每个对象中result，最终将结果返回给我们。
这张支票
if (currentObject.hasOwnProperty(key)) {
