When working on my HTML template in the visual code editor, I encountered the need to declare a variable with type any?

<div class="row">
<div class="col-md-6">
<form #form="ngForm" (ngSubmit)="save(form.value)">
<div class="form-group">

<input #title="ngModel" [(ngModel)]="product.title" name="title" id="title" type="text" class="form-control" required>
<div class="alert alert-danger" *ngIf="title.touched && title.invalid">
Title is required.
</div>
</div>
<div class="form-group">
<label for="price">Price</label>
<div class="input-group">

<input #price="ngModel" ngModel [(ngModel)]="product.price" name="price" id="price" type="number" class="form-control" required [min]="0">
</div>
<div class="alert alert-danger" *ngIf="price.touched && price.invalid">

<div *ngIf="price.errors.min">Price should be 0 or higher.</div>

<option *ngFor="let category of categories$ | async" [value]="category.key">{{ category.payload.val().name }}</option>
</select>
<div class="alert alert-danger" *ngIf="category.touched && category.invalid">
Category is required.

</div>
<div class="form-group">
<label for="imageUrl">Image URL</label>
<input #imageUrl="ngModel" ngModel [(ngModel)]="product.imageUrl" name="imageUrl" id="imageUrl" type="text" class="form-control" required url>

<div *ngIf="imageUrl.errors.required">Image URL is required.</div>
<div *ngIf="imageUrl.errors.url">Please enter a valid URL.</div>
</div>
</div>
<button class="btn btn-primary">Save</button>
</form>
</div>
<div class="col-md-6">
<div class="card" style="width: 20rem;">

product-form.component.ts
import { Component, OnInit } from '@angular/core';
import { CategoryService } from '../../category.service';
import { ProductService } from '../../product.service';
import { Router } from '@angular/router';
import { ActivatedRoute } from '@angular/router';
import 'rxjs/add/operator/take';
@Component({
selector: 'app-product-form',
templateUrl: './product-form.component.html',
styleUrls: ['./product-form.component.css']
})
export class ProductFormComponent implements OnInit {
categories$;
product: any = {};
constructor(
private router: Router,
private route: ActivatedRoute,
private categoryService: CategoryService,
private productService: ProductService) {
this.categories$ = categoryService.getCategories();
let id = this.route.snapshot.paramMap.get('id');
if (id) {
this.productService.get(id).take(1).subscribe(p => this.product = p);
}
}
save(product) {
this.productService.create(product);
this.router.navigate(['/admin/products']);
}
ngOnInit() {
}
}
There seems to be an error in my code, but it does not affect the app's functionality. It compiles into valid JS. By declaring the objects as "any," I was able to resolve the issue.
I would like to explore setting up an interface for this scenario if possible.
