how display child component into a parent component in angular? code example

Example: how to pass variable via component after it's updated angular

// you can try like this, here you want to get the data from the parent component to child component, Here your parent component is ParentComponent and child component is app-child so here for getting the data from parent to child we can use ngOnChanges(changes: SimpleChanges)

// ParentComponent.html

<app-child
[data]="data"
(filterEmmiter)="filter($event)">
</app-child>
// child.component.ts


import {Component, OnChanges, SimpleChanges, Input} from '@angular/core';

class Child  implements OnInit, OnChanges {

    @Input() Data: any; // here is the data variable which we are getting from the parent 

    constructor() {}

    ngOnchanges(changes: SimpleChanges) {
      console.log(changes); // here you will get the data from parent once the input param is change
    }   

}
