javascript find object in array by property value

1const jsObjects = [
2  {id: 1, displayName: "First"}, 
3  {id: 2, displayName: "Second"}, 
4  {id: 3, displayName: "Third"}, 
5  {id: 4, displayName: "Fourth"}
6]

8// You can use the arrow function expression:
9var result = jsObjects.find(obj => {
10	// Returns the object where
11	// the given property has some value 
12  	return obj.id === 1
13})
14
15console.log(result)
16
17// Output: {id: 1, displayName: "First"}

1// To find a specific object in an array of objects
2myObj = myArrayOfObjects.find(obj => obj.prop === 'something');

1//The find() method returns the value of the first element in the provided array that satisfies the provided testing function.
2const array1 = [5, 12, 8, 130, 44];

4const found = array1.find(element => element > 10);
