How to use Array Filter Method In Javascript
In this approach, using the filter() method, we create a function findPropertyValue() to filter objects in the ‘objectsArray’ array based on a specific object id, returning an object property value in the form of a new array containing this particular object property that satisfies the specified condition.
Syntax:
array.filter(callback(element, index, arr), thisValue)
Example: The below code uses the JavaScript array filter method 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) { const property = objectsArray.filter(object => object.id == objectId); if (property[0].name != null) { //If-else condition return property[0].name; } else { return; }}//Prints "name" property value of object with "id" 1console.log(getPropertyValue(1)); |
