How can I update array value with specific condition with angular

Question

I have an external json with a list of names. Something like

{id:1,name:'AAA',age:22},{id:2,name:'AAA',age:100}

I have one of this with an error. I know the right ID. I can't edit the original data.

So, i would like to update the right age in the json before print all data with ng-repat, if ID = 2

How can i update the array with angular?

Loop.. Condition.. Update Object

You can use Array.prototype.map() to iterate the array and set the rightAge for the user with id equal to 2.

Code:

const arr = [{id:1,name:'AAA',age:22},{id:2,name:'AAA',age:100}];
const rightAge = 20; // example right age
  
arr.map(u => u.age = u.id === 2 ? rightAge : u.age);

// Ready to show in the view
console.log(arr);

.as-console-wrapper { max-height: 100% !important; top: 0; }
