amount of returned values - REST API angular

I am using regular REST API with Angular like under the link: https://www.techiediaries.com/angular-by-example-httpclient-get/

In the function:

ngOnInit() {

    this.dataService.sendGetRequest().subscribe((data: any[])=>{
      console.log(data);
      this.products = data;
    })  
  }

can we get into data and get to know how many elements is returned?

I need to know how many elements are returned from backend.

If data is an array simply use length property.

ngOnInit() {

    this.dataService.sendGetRequest().subscribe((data: any[])=>{
      console.log(data);
      this.products = data;
      this.productsLength = data.length;
    })  
  }

The API returns array data: any[]. Javascript Array has length property which shows the total number of items in the array. All you need is to use data.length. If you are dealing with data, then you probably need to know the basics of Array: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array
