How to use For Of Loop In Javascript
In this approach, we create a function findPropertyValue() using a for-of loop to iterate through objects based on a specific object ID, searching for a property’s value accordingly. The matching object property value is returned as the output.
Example: The below code uses the JavaScript for-of loop to find property values in an array of objects.
Javascript
const objectsArray = [ { id: 1, name: "w3wiki" }, { id: 2, name: "Computer Science" }, { id: 3, name: "Portal" }, { id: 4, name: "For Geeks" }, { id: 5, name: "GFG" },]function getPropertyValue(objectID) { for (const obj of objectsArray) { if (obj.id == objectID) { //If-else condition return obj.name; } else { continue; } } return null;}//Prints "name" property value of object with "id" 3console.log(getPropertyValue(3)); |
Output
