Object.assign 对象数组

Question

所以我可以在这样的对象上使用 object.assign

let recipe = {"recipeId":1,"title":"Instant Pot® Chicken and Wild Rice Soup","directions":"Lorem ipsum dolor sit","imageLink":"https://images-gmi-pmc.edge-generalmills.com/60c3ebda-50a7-415e-8c66-14f6c9b93034.jpg","id":"1"}
this.editableRecipe = Object.assign({},recipe);

但是我在处理像这样的对象列表时遇到了问题：

let ingredients = [
    {"ingredientId":1,"amount":1,"unit":"package","ingredient":"(20 oz) boneless skinless chicken thighs","note":"patted dry","id":"1"},
    {"ingredientId":2,"amount":1,"unit":"teaspoon","ingredient":"salt22323","note":"","id":"2"},
    {"ingredientId":3,"amount":0.5,"unit":"teaspoon","ingredient":"pepper","note":"","id":"3"},
    {"ingredientId":4,"amount":2,"unit":"tablespoons","ingredient":"butter","note":"","id":"4"},
    {"ingredientId":5,"amount":1,"unit":"package","ingredient":"(20 oz) boneless skinless chicken thighs","note":"patted dry","id":"5"},
    {"ingredientId":6,"amount":1,"unit":"teaspoon","ingredient":"salt","note":"","id":"6"}
];

// this.editableIngredients = something for object assign for the array here

从我读到的内容来看，array.map 方法可能是最好的方法，但我在正确使用时遇到了一些问题。

基于this我尝试了这样的事情：this.editableIngredients = ingredients.flat().map(p => Object.assign(p));

也根据阅读尝试了一些不同的迭代this

[更正x2] 也许是这样的：

copy = ingredients.map(o=>Object.assign({},o))
