We use the Array.find() method to find the first element that meets a certain condition. In that case, you need the find() method. We just need one element that matches the condition. There are times when we don't need all the elements that meet a certain condition. You can read more about this method here. If no item in the array meets the condition, an empty array is returned. callback is the callback function that is applied to each element of the array.array is the array on which the filter method is called.

newArray is the new array that is returned.The syntax for using the array.filter() method is the following: let newArray = array.filter(callback) For instance, if we want to get all items in an array of numbers that are greater than 10, we can do this: const array = Ĭonst greaterThanTen = array.filter(element => element > 10) We can use the Array.filter() method to find elements in an array that meet a certain condition. In this article, we will discuss four methods we can use to search for an item in an array. Which method you choose depends on your specific use case.įor instance, do you want to get all items in an array that meet a specific condition? Do you want to check if any item meets the condition? Do you want to check if a specific value is in the array? Or do you want to find the index of the value in the array?įor all these use cases, JavaScript's Array.prototype methods have you covered. There are different methods in JavaScript that you can use to search for an item in an array.
