Is Chrome’s JavaScript console lazy about evaluating objects?

Closed yesterday.
I am attempting to get the innerText from the body of the website to print to the console and I am not sure what I am doing wrong.
The following code I have works with listing all content of the body:
console.log(document.getElementsByTagName('body'));
but when I use the following:
console.log(document.getElementsByTagName('body')[0].innerText);
I get an error and there's no output.
I was expecting for the console output to show the innerText of the body.

Do DOM tree elements with IDs become global properties?

Is there a spec that the id of elements should be made global variable?

What is better and what is the difference (performance, browser support...)?
I thought that DOM elements that have an id automatically create in a window object so you don't need to find them in DOM through getElementById. Am I right and what problems it could bring? I can't find any documentation on such a possibility of js window object.
Examples with window:
window['elementId'];
window.elementId;
The same result as getElementById and querySelector

My project is about generating random sentences. How do I make it from here, so that the program picks a random sentence from the index, and displays it on the screen? Please help.
It says that the '$ is not declared'.

My coding picture.
All you need to do is include jQuery in your HTML file like so:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script

Understanding Polymer data-binding and HTML tags
(1 answer)
Closed 7 years ago.
I'm trying to lean Polymer and I'm looking at this tutorial.
The problem that i'm experiencing is a the Declary a property section, if i don't put the template {{owner}} in a span or b it doesn't get interpreted.
So my question is basically if this works
This is <b>{{owner}}</b>'s configurable-name-tag element.
Why doesn't this ?
This is {{owner}}'s configurable-name-tag element
Notice the missing <b>.

This is because Polymer v1, unlike v0.5, doesn't support string concatenation.
The binding annotation must currently span the entire content of the tag, as you can read on the official documentation: https://www.polymer-project.org/1.0/docs/devguide/data-binding.html#binding-to-text-content
