What’s the point of <script> elements in an HTML doc?

In a previous blog, I explored scripting languages and shell/bash scripting.

This exploration was spurred by “scripting” being thrown around in job descriptions which made me ponder what little I knew of “scripts” and “scripting” in the programming universe. Here, I’m going to revisit <script> as an HTML tag since that’s the first form I’ve seen it as.

As a basic <script> tag it can allow access to another document (such as a JavaScript doc) or to other sources to be used for something like Bootstrap.
