Are external links linked to javascript so the browser waits for them to load?

Question

When your page is parsed, and it meets <script src='someExternalSite/jquery.js'></script>or something else, does the page wait before this file is loaded and accessible before continuing with the parsing?

Added:

Most browsers load all scripts at the same time to save time (even if they run in order)?

Answer 1

each tag blocks the page from further rendering until the js file is fully loaded. It’s a good idea to place the js file at the end of the body tag

script?

Answer 4

All major browsers should try to get these files synchronously, because the next script in the list may rely on one of them earlier.

Answer 5

Yes, that’s why people recommend adding scripts immediately before the tag </body>or using the attribute defer.
