10/30/2023 0 Comments Find object in array javascript![]() ![]() It then returns the position of the array element or -1 if no element passes the test. The findIndex() method takes a function containing a test as an argument and applies it to each element of the array without making any changes to the original array. ![]() Find Index of Object With findIndex() Method This method is a lot more elegant, but sadly it doesn’t work on old browsers. The find() method executes a function for each array element. JavaScript ES6 introduced a new method called findIndex(). The find() method returns the value of the first element that passes a test. We could have used the map function to get the value of any property and get the index of the object based on that property. ![]() Lastly, we used the indexOf() method to get the index of the object whose age property is 45 and printed it to the console. We then used the map function to just get the ages of employees in a separate array. The objects contain data of different employees. In the above code, we first defined an array which contains two objects. Here’s a demo on jsFiddle for you to play around with.Let employees = Array.find is a very useful function but only if you can determine whether or not you have the right item independently from other items in the array, e.g. Array.find() We use the Array.find() method to find the first element that meets a certain condition. However, these methods are quite limited because they return the index. Let's check them out!įirst, let's say that we have this array of objects called "objArray": var objArray = [ In that case, you need the find() method. In ES5, to find an element in an array, you use the indexOf() or lastIndexOf() methods. Here, the find () method returns the first array element provided that satisfies the given testing function. There are A LOT of ways of achieving this, so I decided to put some of them together in this post to make it easy for you to pick up whatever works best for you. Find Object in Array by Property Value Using the find () Method We can use the find () method to find an object in an array of objects in JavaScript by its property value. You may have seen yourself in this situation when coding in JavaScript: you have an array of objects, and you need to find some specific object inside this array based on some property of the object. ![]()
