Find a value in an array of objects in Javascript

Finding a Value in an Array of Objects in JavaScript 🕵️‍♂️

Have you ever found yourself in a situation where you have an array of objects in JavaScript and you need to find a specific object based on a certain property value? Well, you're not alone! In this blog post, we'll explore how to tackle this problem effectively and efficiently.

The Problem 🤔

Let's take a look at the scenario presented by our fellow coder. They have an array of unnamed objects, which in turn contain an array of named objects. The goal is to find the object where the "name" property is equal to "string 1". Additionally, they also mentioned that they want to replace the found object with an edited one.

The Solution 💡

To solve this problem, we can leverage the power of JavaScript's array methods.

var array = [
    { name: "string 1", value: "this", other: "that" },
    { name: "string 2", value: "this", other: "that" }
];

One of the simplest approaches is to use the find method, which returns the first element in the provided array that satisfies the provided testing function. In our case, the testing function will check if the "name" property matches the desired value.

var desiredObject = array.find(function(obj) {
    return obj.name === 'string 1';
});

if (desiredObject) {
    // Perform the desired operations with the found object
    // For example, replace it with an edited object
    Object.assign(desiredObject, { name: 'edited string 1', value: 'new value' });
}

Alternatively, you can use the more concise arrow function syntax:

var desiredObject = array.find(obj => obj.name === 'string 1');

if (desiredObject) {
    Object.assign(desiredObject, { name: 'edited string 1', value: 'new value' });
}

💡 Pro Tip: To find multiple objects that match the desired criteria, you can use the filter method instead of find.

And that's it! With just a few lines of code, we were able to find the desired object and perform any required operations on it.
