Showing" Property 'emit' does not exist on type '() => void' "alouugh I included EventEmitter class

I am making a basic angular js web page and facing an issue regarding the emit function

Here’s app.component.ts

import { Component } from '@angular/core';
import { WishItem } from '../shared/models/wishItem';

const filters =
  [
    (item: WishItem) => item,
    (item: WishItem) => !item.isComplete,
    (item: WishItem) => item.isComplete
  ]

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrl: './app.component.css'
})
export class AppComponent {

  //items is an array
  items: WishItem[] = [
    new WishItem('To Learn Angular'),
    new WishItem('Get Coffee', true),
    new WishItem('Find grass that cuts itself')


  ];
  listFilter: any  = '0';

  //fromWishItem.ts

  title = 'wishlist';

  //copying items array
  get visibleItems(): WishItem[] {

    return this.items.filter(filters[this.listFilter])

//changing dynamically
  }

}

Here’s my child component add-wish-form.componenet.ts

import { Component, OnInit ,Output,EventEmitter} from '@angular/core';

import { WishItem } from '../../shared/models/wishItem';

@Component({
  selector: 'add-wish-form',
  templateUrl: './add-wish-form.component.html',
  styleUrl: './add-wish-form.component.css'
})
export class AddWishFormComponent implements OnInit
{
  
@Output() addWish = new EventEmitter<WishItem>();
/** EventEmitter facilitates communication between the child and parent components
 * 
 */

constructor(){ }
  ngOnInit(): void {
      
  }


  newWishText = '';

  addNewWish()//add wish to the items array above & clear textbox
  {
    //adding new wish item in our array
    

    this.addNewWish.emit(new WishItem(this.newWishText))
    this.newWishText = '';

  }

}

I’m using Angular CLI: 17.0.3
Node: 21.2.0

I was following a tutorial video from yt where it seems working but in my laptop it’s not working.
Anyone can tell me a solution to this issue?

>Solution :

You have a typo, its referring to the source function instead of the event emitter!

Before:

this.addNewWish.emit(new WishItem(this.newWishText))

After:

this.addWish.emit(new WishItem(this.newWishText))
