[@veerlamuralikrishna4774]

simple way
let obj =[1.2,3]
console.log({...obj})

[@Spider-Man_67]

Easy way
// Convert an array into an object.
const names = ['Rahul','Krityveer','Anish','Gopal','Parveen'];
const obj = {...names }
console.log(obj);

[@n_fan329]

still not 100% correct, in this case keys are not identical to the values

[@aliarslanansari]

@@n_fan329 no one want keys identical to values

[@jayatighosh4626]

let arr = ['Sun', 'Moon', 'Star']
// Convert array to object
let obj = {};
let contertToObj = arr.forEach(i=>obj[i] = i);
console.log(obj)
// Convert object to array
let newArr = [];
Object.keys(obj).map(key=>newArr.push(key));
console.log(newArr)

[@faizalkhan2437]

Object.entries(obj) or if you wanna iterate the value only so you can go with object. Values(obj).

[@AmritpalSingh-sw3bl]

Using for each loop we can handle it easily

[@adarshkhatri993]

Object.keys(), Object.values(), Object.entries() to convert into array??

[@semicolon6499]

Ha

[@vaibhav_gamingg]

Bhaii ap kese kr rhe ho sb

let obj = arr.reduce((a,it,i)=>{
a[it] = it
return a
},{})
console.log(obj)
//{ a: 'a', b: 'b', c: 'c' }

let obj={};
for( let i=0 ;i

[@coderdost]

Yes that will also work

[@vishal10471]

Arr.reverse

[@pankajsharma-rf1ov]

My question is why it is taking only the last one in case of string means
({...a,it:it}) o/p {it:"a"}
But why ({...a,[it]:it}) gives right answer
I am still not clarified.

[@coderdost]

When you put a square bracket on key of an object. The variable is evaluated and then the result is assigned as key string. This feature is used a lot in forms.
{[e.target.name]:e.target.value} this kind of syntax you will see in lot of frontend forms..

[@pankajsharma-rf1ov]

@coderdost after over a time I realised that when the data is entered in the object like {it:"a"} and in further iteration data is entered with different value but with the same key that's why our last key value is modified or replaced with new one bcz key is the same.

[@coderdost]

👍🏻 yes

[@user-tg1wd2xb6j]

Aap kaun sa code editor use karte ho. yeah console ki command bhi code mein hi Dikhai ja raha hai ya aap kaise kar rahe ho.
Aap ko subscribe Kar Diya Hai Ab lajmi batana.

[@coderdost]

VScode with Quokka JS extension

[@jamshedahmad6069]

Using the Object.assign() method to convert an array to an object ,e.g. const obj = Object.assign({}, arr).
Using the spread syntax (...) to convert an array to an object, e.g. const obj = {...arr}.
Using the Array.forEach() method to iterate over all items and add them as a key-value pair to an object.
Using the Object.fromEntries() method to convert an array of key-value pairs to an object, e.g. const obj = Object.fromEntries(arr).

[@coderdost]

Boss kuch samajh mein nahin aya . And funny part is i know programming. Mujhe kuch knowledge hoke agar samajh nahin aya dusre ko kya aega

[@coderdost]

these are just tricky question ppl ask sometime in interviews. They are not normal in everyday work of JS developer. But good for practice.

[@hishamkhan4913]

Bro .. coding se upar he javascript... Js padho sahi se... He explained perfectly...

[@unknowneditor2799]

My question is that can program understand who is subject and object in array sentence ?

[@coderdost]

program must use some library to understand that language, other wise by simple logic its not possible.

[@akash.web_dev]

const arr=['a','b','c']
let obj = Object.assign({},arr)
console.log(obj);
let array= Object.entries(obj)
console.log(array.flat());
array to object and object to array
ye ek good approch hai ya nahi
