I would like to know how to merger and overwrite the already existed object value in nested array in javascript.

As shown below, i need to merge the other_obj to obj with id = "zen" and overwrite if the property exists else merge

var obj =[
id:"abc", 
amount: "100", 
fee: "5.5",
id:"xyz", 
amount: "1000", 
fee: "5.5",
id:"zen", 
amount: "500", 
fee: "5.5"]

var other_obj = 
amount: 600,
name: "new"



Expected Output: 

id:"zen",
amount: 600,
fee: "5.5",

Use ... spread syntax:

var obj = [
 id: "abc",
 amount: "100",
 fee: "5.5"
 ,
 
 id: "xyz",
 amount: "1000",
 fee: "5.5"
 ,
 
 id: "zen",
 amount: "500",
 fee: "5.5"
 
];

var other_obj = 
 amount: 600,
 name: "new"
;

var test = ;
obj.forEach(e => test = ...test, ...e);
test = ...test, ...other_obj;
console.log(test);
