i am stuck with jasmine and need help.
I read/youtubed/googled but seems like i am on the wrong track...

I am learning protractor to automate angular pages written with typescript.

in the 1st example, I used angularjs page to pull few things and they seem to be passing. 
I am trying 2nd example to pull items from angular.io page and i am not sure... anything i try fails.

Here is what i have so far:
i used protracto --elementExplorer to pull items from http://www.angular.io
> element(by.css('.nav-link')).getText()
[20:31:44] W/element - more than one element found for locator By(css selector,
.nav-link) - the first result will be used

5 center links
> element.all(by.css('.nav-link')).getText()
[ '', 'FEATURES', 'DOCS', 'RESOURCES', 'EVENTS', 'BLOG' ]

search textbox
<input aria-label="search" placeholder="Search" type="search">
> element(by.tagName("input")).getText().click().clear().sendKeys("tutorial")
null
>
> element.all(by.css(".button.hero-cta")).getText()
[ 'GET STARTED' ]
> element(by.css(".button")).getText()
[20:45:35] W/element - more than one element found for locator By(css selector,.button) - the first result will be used
GET STARTED

> element.all(by.css(".button")).getText()
[ 'GET STARTED', 'LEARN MORE' ]


links on bottom footer blocks
> element.all(by.css(".footer-block")).getText()
[ 'RESOURCES\nAbout\nResource Listing\nPress Kit\nBlog',
  'HELP\nStack Overflow\nGitter\nReport Issues\nCode of Conduct',
  'COMMUNITY\nEvents\nMeetups\nTwitter\nGitHub\nContribute',
  'LANGUAGES\n???' ]

firstSpec.ts works fine for angularjs page
i added secondspec.ts below 

import { ElementFinder, browser, by, element } from 'protractor';
describe('angulario homepage verify list', function () { //Suite in Jasmine
  it('should check top 5 link buttons', function () { // Test in Jasmine
    browser.get('https://angular.io'); // Entering application url in browser
    element.all(by.css('.nav-link')).getText()); {
    //expect statement goes here
      
   });
  });
});

i am trying to ensure 5 links on the center top are present and get the names with count of 5... 

It seems so trivial when watching videos, but when i try to implement it, nothing works.

Thanks
