2017-03-20 · JavaScript : find an object in array based on object's property (and learn about the "find" function) Published on March 20, 2017 March 20, 2017 • 341 Likes • 52 Comments.

Just like the filter method, it takes a callback as an argument and returns the first element that meets the callback condition.
arr.find () function is used to find the first element from the array that satisfies the condition implemented by a function. If more than one element satisfies the condition then the first element satisfying the condition is returned. Suppose that you want to find the first odd number in the array.

Either you need to use one loop or you can use any other methods provided in ES6. Loop is not a good option. JavaScript provides a couple of different methods that makes it more easier. Note that, JS find() method is truly different from the findIndex() method.
