$.extend assign 对象合并

var object1 = {
    apple: 0,
    banana: {weight: 52, price: 100},
    cherry: 97
};
var object2 = {
    banana: {price: 200},
    durian: 100
};

将object2 合并到 object1 中

1.jquery用法：

　　$.extend(object1, object2);
　　console.log(object1); //{apple: 0, banana: {price: 200}, cherry: 97, durian: 100}
  2.ES6用法：

　　Object.assign(object1, object2);
　　console.log(object1); //{apple: 0, banana: {price: 200}, cherry: 97, durian: 100}
