How to return a modified object after updating all the values in it?

I need to add single quotes to all the values in an object that looks like this:

{name: "testUser", type: "regular"}

The object needs to look like the following:

{name: "'testUser'", type: "'regular'"}

I'm using Object.values to achieve this:

Object.values(targetObject).map(value => value = `'${value}'`)

Except it's not exactly updating targetObject. What would be the correct way to achieve this?

You can you for..in to loop through properties of the object.

const obj = {name: "testUser", type: "regular"}

for (let k in obj){
 obj[k] = `'${obj[k]}'`
}

console.log(obj)

You can use Object.entries to iterate through all the entries in the object and update them:

const obj = {name: "testUser", type: "regular"};

for (let [key, value] of Object.entries(obj)) {
  obj[key] = `'${value}'`;
}

console.log(obj);

You could map new objects and collect them to a single object.

var object = { name: "testUser", type: "regular" },
    updated = Object.assign(...Object.entries(object).map(([k, v]) => ({ [k]: `'${v}'` })));

console.log(updated);

To update the original object, you'll need the key. Use Object.entries() to get the key and value, iterate with Array.forEach(), and each key with the new value:

const targetObject = {name: "testUser", type: "regular"}

Object.entries(targetObject) // get an array of [key, value] pairs
  .forEach(([k, v]) => targetObject[k] = `'${v}'`) // update the original object keys

console.log(targetObject)
