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
