Transforming an item into a textual format

Question

Transforming an item into a textual format

I am looking to transform an object by replacing any falsey values with "All" and then converting the object into a single string. Initially, I attempted using the .reduce method, which successfully replaces falsey values. However, I am struggling to find an elegant solution to format the object such that each key-value pair is separated by commas within the same string.

const object1 = {
  a: 'somestring',
  b: 42,
  c: false,
  d: null,
  e: 0,
  f: "Some"
};

let newObj = Object.keys(object1).reduce((acc, key) => {
    
  if(!object1[key]){
    object1[key] = "All"
  }
  
  return {...acc, [key]: object1[key]}
    
  
}, {})

console.log(Object.entries(newObj).join(":"));

My desired output should be

"a: somestring, b: 42, c: All, d: All, e: All, f: Some"

Answer №1

here is an example of how you can achieve this

const testObject = {
  name: 'John',
  age: 30,
  city: 'New York',
  isActive: true
};

const resultString = Object.entries(testObject).map(([key, value]) => `${key}: ${value ? value : 'N/A'}`).join(',')

console.log(resultString)

const myObject = {
  firstName: 'John',
  age: 30,
  isStudent: true,
  car: null,
  siblings: 2,
  hobby: "Reading"
};

let updatedObj = Object.keys(myObject).reduce((accumulatedObj, prop) => {
    
  if(!myObject[prop]){
    myObject[prop] = "Unknown"
  }
  
  return {...accumulatedObj, [prop]: myObject[prop]}
    
  
}, {})
const result = JSON.stringify(updatedObj) 
console.log(typeof result)

This code snippet will output "string" to the console :)

Perhaps this information could be of assistance,

const data = {
  name: 'John',
  age: 30,
  active: true,
  points: null,
  level: 0,
  status: "Pending"
};

const stringifyObject = Object.keys(data)
  .reduce((previous, key, index) => previous + `${key}: ${data[key] || "N/A"}, `, "")
  .slice(0, -2);

console.log(stringifyObject);

// name: John, age: 30, active: true, points: N/A, level: N/A, status: Pending

One possible solution is to create a custom function for this task, such as:

var stringifyObject = function(object){
  if(object instanceof Object){
    let objKeys = Object.keys(object);
    let str = "";
    
    for(let key of objKeys){
      object[key] = object[key] == null ? "all" : object[key];
      
      if(str !== ""){
        str += ", ";
      }
      
      str += key + ":" + object[key];
    }
    return str;
  }
  return "";
}

Using this function will give you the desired outcome.
