On the latest Angular 6 version, in order to work, you will have to comment out the default import { EventEmitter } from 'events' and include EventEmitter from '@angular/core' I don't really know what is the EventEmitter from events is, they have the same name but different purpose it seems. Can anyone explain this?

[@Codevolution]

The video is reflects Angular 5 but it has changed in Angular 6 as you point out. I will pin this comment so that it will be helpful for others with the same problem. Thanks

[@idlevandal69]

Has the video been updated? He is importing EventEmitter from @angular/core at 5:50

[@johan_maximus]

You saved my life (Y)

[@vatsalshah6505]

[@endrefidje5698]

Will there be an updated version of these Angular tutorials based on Angular 7? Seems to be a few things "broken" now.

[@Skaxarrat]

I just found your tutorials and I'm enjoying them. This is my 15th video in a row :) Can you do sometimes videos doing small projects (20-60 min vídeos) where you create a small SPA? This way we could learn how to put every thing we learnt together.

[@ABsazerNer]

You tutorials are always the best, cause you always teach with examples, keep up 👍

[@VolodymyrM_UA]

If you get "Can't bind to 'parentData' since it isn't a known property of 'app-test'" error message, check if your test component's selector is defined as Tag: 'app-test' (and used as custom HTML tag: in the app component). Because Class selector: '.app-test' () and Attribute selector: '[app-test]' ( ) will not work, with the above error.

[@betterahyosi]

[@zaraoberain9138]

Good explain man : )

[@deepumon.d3148]

Nice explanation.

[@mdfarooq97]

One of the best, to-the-point Angular tutorials. Great Job! Keep it up! I would like to know something more about the component interaction, I have a case where components are not in parent-child relationship and I would like to communicate between them using events, is this possible? For example, There is AppComponent which holds two other components inside it, ComponentA and ComponentB, will it be possible for ComponentA to send events to ComponentB?

[@naveenm283]

yup I am stuck in the same situation

[@kishanlal676]

Why don't you pass the data from ComponentA to Parent and Parent to ComponentB? I don't know whether there is any straightforward solution for this.

[@arnabmondal5596]

Can we pass an object to the parent thru event and assign it to a property in parent component?

[@rutujagurav466]

Awesome tutorial

[@gajalvasita2443]

Nice Work

[@nellyville8657]

Hi, plz, have you succed with EventEmitter()...? Mine doesn't work

[@syawalnazir4676]

great job Vishwas. I enjoyed learning the basics from your videos. I have a question regards to this child and parent. Can the data using @output from test.component.ts sends to app.components.ts or app.components.html and that being called in instead of

[@amirdar116]

.ts file because we are sending value to properly declared in component class of parent

[@naeemjamali1475]

Good job, keep it up!

[@eyotajr]

when sending data from child to parent i can use the data without redeclaration the data on the parent.. is there some kind side effect because i don't redeclare the data on parent that sent by the child compt?

[@hadowman6847]

Very best explanation : my dawg => Thanks !

[@harshilparmar9076]

thank you so much brother

[@JV-vp5vl]

Hi, nice tutorial! Are parameters passed by value or by reference when interacting between components, and also when calling functions in the same component?

[@gvinianidzegivi]

Great course !!!

[@SSR2902]

[@rexsam3134]

Do you have any videos on communication between 2 child components?

[@karthick8810]

[@ankitagupta6232]

[@suyashchirme4887]

[@umairali2360]

@@TeluguCartoonist dear my error was in view. and now i did not remember exactly how i solve it, because i am working on laravel

[@deepthik9500]

Hi, In react why we can't send the data from child to parent. In underhood what is the difference between the angular and react.

[@jaypatel2471]

In React, data flow is typically unidirectional, from parent to child, and communication from child to parent is achieved using callback functions passed as props. In Angular, you can use @Output and EventEmitter for child-to-parent communication, and it also provides a more extensive system for component interaction, including services and dependency injection. React is a library for building UI components, while Angular is a complete framework with a more opinionated structure and additional features.

[@imrohan97]

can we use name of property different from parentData in app-component template?

[@UdayNand7]

what if we want to send method from parent to child
