Find Object In Array With Certain Property Value In JavaScript
July 7, 2020 by Andreas Wik
If you have an array of objects and want to extract a single object with a certain property value, e.g. id should be 12811, then find() has got you covered.
My array:
const students = [{
id: 14400,
name: 'K. Kelly',
year: 2
}, {
id: 12811,
name: 'A. Potter',
year: 3
}, {
id: 22198,
name: 'J. Simpson',
year: 1
}]
I want to find the object with an id of 12811. find() takes in a testing function. We want the object’s id property to match our variable id‘s value.
const id = 12811
const student = students.find(element => element.id === id)
console.log(student.name)
// "A. Potter"
JSFiddle:
Note: find() stops iterating over the array when it finds the first match and returns it. If you want to fetch multiple array items, then check outĀ filter instead.
Hope it helps.
