Why doesn't Angular work correctly?

Question

JavaScript

I wrote the simplest server on Node.js / Express, which simply gives index.html, the page loads, but instead of the template and data, this is how I see my tag, which is described in the directive. By the way, if you refresh the page, then 1 out of 10 times it works correctly, but it’s not possible to work like that. There are no errors in the console, I tried to load angular from cdn and from a local file, I inserted it at the beginning and at the end of the file, the result is the same. What's the matter?

And here is 1 out of 10 cases

Answer 1

Because scripts are executed before the body of the pages is loaded, move the script blocks to the end of the body.
