![]() ![]() It then returns the position of the array element or -1 if no element passes the test. Assuming obj is the obj (parse the json to obj like JSON.parse (obj) before you do this), obj.find (item > item.id 6) should get you the item. 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 The find() method executes a function for each array element. This method is a lot more elegant, but sadly it doesn’t work on old browsers. The find() method returns the value of the first element that passes a test. JavaScript ES6 introduced a new method called findIndex(). ![]() ![]() 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. Methods are actions that can be performed on objects. Object Methods Objects can also have methods. Lastly, we used the indexOf() method to get the index of the object whose age property is 45 and printed it to the console. JavaScript objects are containers for named values called properties. We then used the map function to just get the ages of employees in a separate array. Here is the JavaScript program to find an object by id using find() method in. The objects contain data of different employees. It will return undefined if the condition is not satisfied by the array element. In the above code, we first defined an array which contains two objects. ![]()
