#21 For in loop in JavaScript

[@aravind2377]

Answer for 3:28 , I have used in my coding with help of phones instead of laptop. let alien = { name : 'Chandramouli', tech : 'Javascript', phones : { android_version : '11', ram : '4', brand1 : 'mi' } } for(let key in alien.phones) { console.log(key, alien.phones[key]); } Output : android_version 11 ram 4 brand1 mi

to get keys of laptop key : for(let key in alien.laptop){ console.log(key) } to get values of laptop keys : for(let key in alien.laptop){ console.log(alien.laptop[key]) } //Alternative for(let key in alien["laptop"]){ console.log(key) }

[@SalmanulFaris-zv6qy]

this will only print the values of properties eg: i7,4, asus

[@WenboWang-u8b]

for(let key in alien['laptop']){ console.log(key, alian['laptop'][key]) }does it work.

[@muskangupta680]

let Employee={ name:"Muskan", age:22, course:{ main_subjects:'Mathematics', 'minor subject':'English'} }; for (let key in Employee.course){ console.log(key,Employee.course[key]); } output:- main_subjects Mathemaics minor subject English

[@bonnyrogny241]

its correct😶

[@kheiromahiout7483]

The answer of 3.38 is: For(let key in alien["laptop"]{ Console.log(key, alien.laptop[key])}

[@sandeepprabhakula7714]

for(let key in alien.laptop){ console.log(key,alien.laptop[key]); } I think it should work

[@santoshsuryavamshi888]

Good it's working.

[@sshreeeditz640]

Its working. Spr👏

[@nocontentshere8116]

for(let key in alien){ console.log(key,alien.laptop.key); } might think this will also work. and in for don't need to denote the inside object, can directly take whole object

I came back from the last video, here is my shortcut code: (it works even if the object has multiple objects in it): function key_printer(obj, spaces = '') { for(keys in obj) { if(typeof obj[keys] != 'object') { console.log(spaces + keys); } else { console.log(spaces + keys); key_printer(obj[keys], spaces + ' ') } } } key_printer(objects) //Note: The word 'objects' is the object name. This works...

[@blackpanther-vr6yj]

[@maverick_8707]

to print the value of the object we can do this for (const key in alien) { if (Object.hasOwnProperty.call(alien, key)) { const element = alien[key]; console.log(element); } }

Answer for 3:28 || for (key in alien.laptop) { console.log(key, alien.laptop[key]) }

thanks so much Navin, i am loving the series , i took your python course and i enjoyed it. you know how to simplify everything to make it possible for us to learn. thank you so much

[@yazor8716]

for (let key in alien) { if (typeof alien[key] === "object") { for (let key2 in alien[key]) { console.log(key2, alien[key][key2]) } } else console.log(key, alien[key]) } I run it, it works :) Edit: I might have misunderstood the objective. Not sure if we were supposed to print the inner object's properties only. In any case, this program prints the properties of both objects.

[@bhumit070]

yes it is okay, but better to wrap it inside function you can see my comment

[@yazor8716]

@@bhumit070 I am assuming you made it recursive so that it can print multiple nested objects, right? Good thinking!

[@tomasmatusek6292]

realy good waw.Something like that I was try find, u are good.

[@tomasmatusek6292]

that is realy perfect and is interesting that if you dont use alien[key],only alien[key2]it not work good, so you must use alien[key][key2], that is realy interesting. And same thanks for this else, realy good if we dont have objects in laptops, GJ bro.
