JavaScript/React - Update a value in array with particular key name from a array of arrays

Question

In the below array of arrays I need to update the id value for a particular name.

objArray = [{ name: John, id: 12}, { name: Jake, id: 45}, { name: Jacob, id: 78}];

Ex: If user enters a name and id in text boxes and clicks submit I want to update the id in the array for the particular name.

I can accomplish this using for loops but can you please let me know the most efficient way to do this in Java Script/React?

Answer 1

Use the find function and set the entered name.

Look at this code snippet

let objArray = [{  name: "John",  id: 12}, {  name: "Jake",  id: 45}, {  name: "Jacob",  id: 78}];

let name = 'Jake'
let newId = 59;
objArray.find((o) => o.name === name).id = newId;

console.log(objArray);
