TypeScript Array Object.entries() Method Last Updated : 15 Jul, 2024 Summarize Comments Improve Suggest changes Share Like Article Like Report The Object.entries() method in TypeScript is used for creating an array of key-value pairs from an object's keys and values. This method simplifies the process of iterating over an object's properties and enables easier data manipulation.SyntaxObject.entries(obj);Parameterobj: It takes the object as a parameter whose key-value pair you want to store in the array.Return ValueThe method returns an array of arrays. Each nested array contains a key and a value pair from the object.Example of TypeScript Array Object.entries() MethodExample 1: In this example, we are going to create key-value pairs from the given person object. TypeScript interface Company { name: string; workForce: number; } const person: Company = { name: "GeeksforGeeks", workForce: 200, }; const personEntries = Object.entries(person); console.log(personEntries); Output: [ ["name", "GeeksforGeeks"], ["workForce", 200] ] Example 2: In this example we are going to extract key-value pairs from the given product list. TypeScript interface Product { id: number; name: string; price: number; } const products: Product[] = [ { id: 1, name: "Apple", price: 1.99 }, { id: 2, name: "Banana", price: 0.79 }, { id: 3, name: "Orange", price: 1.25 }, ]; const productEntries = Object.entries(products); console.log(productEntries); Output:[ [ '0', { id: 1, name: 'Apple', price: 1.99 } ], [ '1', { id: 2, name: 'Banana', price: 0.79 } ], [ '2', { id: 3, name: 'Orange', price: 1.25 } ] ] Comment More infoAdvertise with us Next Article TypeScript Object The Array Type P pankajbind Follow Improve Article Tags : TypeScript Similar Reads TypeScript Array entries() Method The Array.prototype.entries() method in TypeScript returns a new array iterator object that contains the key/value pairs for each index in the array.
