It’s that easy!Īs you’ve seen, you can find values of every data type in a JavaScript array. In the example above, we compare a few property values in the isBetween function, which returns a boolean to the find method. In this case, we modify the string to lowercase characters in the example above to match even though the capitalization isn't equal. Array.find is a simple but incredibly useful method for searching JavaScript arrays. You can check if a property value equals a value by returning this with the arrow function project.type = 'value'. You are free to use it because it’s free on NPM and GitHub 😉 import, ] console.log(projects.find((project) => () = 'development')) console.log(projects.find((project) => isBetween(dateNumber('')).min(dateNumber(project.startDate)).max(dateNumber(project.endDate)).calc())) You can calculate if a specific value is between a minimal and a maximum number. This function will not operate if the array elements are empty, and it will not affect the original array. It verifies all of the array’s elements, and the first element that meets the criterion is printed. With the second example, we try to find a project where ‘2024–01–27’ is between the startDate and the endDate.Ī few years ago, I created a package is-between-js for my personal usage. In Javascript, the arr.find () method is used to acquire the value of the first element in the array that meets the given criterion.
In the example below, we try to find the first project with the type of ‘development’. When you want to find a property value in an array of objects, it is as easy as with singular values. Find an object property value in the array.
