如何将对象转换为 Typescript 中的列表

Question

I want to convert my object to list while passing as param to my API. I am not sure how to achieve this. I tried Object.keys but not getting expected output.

Object.keys(myobj).map(function(key){
---logic
});

I am receiving list of objects from API:

[{Name : "sachin",Age  : 30},{Name : "Ramesh",Age  : 35}]

In Angular, when I use find method it is converted as object from the above list and it looks like below.

 {Name : "sachin",Age  : 30}

Now I have to change Age property value as 42 and pass it to API as list.

[{Name : "sachin",Age  : 42}]

Can someone help me to achieve this result.

Answer 1

You can use this:

var payload = [{...prevObject,...{
  Age: 42
}}];

prevObject is object returned from find method.

Basically, the ... (spread operator) is used to merge the two objects into one.
