By default, object keys are returned as strings, but it is possible to return them as a method.
The steps are follows:
- Get the object keys.
- Assign function to every key.
- Assign them to an object.
- Return the object.
Example 1: The above approach is implemented using JavaScript functions Object.keys() and forEach().
Javascript
let person = { name : "Raktim Banerjee", email: "example@gmail.com"} const getObjectKeyAsMethod = obj =>{ let newObject = {}; //returned object keys in an array Object.keys(obj) //iterate the array .forEach(key => { //assign function to key newObject[key] = function(){} }) return newObject; } let result = getObjectKeyAsMethod(person); console.log(result); |
Output:
Example 2: The following code is implemented using Object.entries() and ‘new Function‘ .
Javascript
let person = { name : "Raktim Banerjee", email: "example@gmail.com"} let result = {} for(let [key] of Object.entries(person)){ result[key] = new Function() } console.log(result); |
Output:
object keys function
