I have seen a few tutorials about $broadcasting in angularjs, and I know the angular(2 ) isn't the same thing, so I want to ask if $broadcast and $emit are included in angular(2 ) or $broadcast and $emit functionalities are achievable using @input and @output?

CodePudding user response：

In angular 2 , you could use subjects and behaviour subjects to achieve broadcast and emit functionality. @Input and @output only works for parent child
