Question

How do you include an external JavaScript file in HTML?

Answer

You link an external JavaScript file with a <script> tag whose src attribute points to the file's URL.

<script src="TextStatsLib.js"></script>

The browser loads and executes the JavaScript file at that point in the page. Functions defined in the external file become available for use in subsequent scripts or HTML event handlers.

Question

What is the difference between a JavaScript library and a framework?

Answer

You call a library's functions, whereas a framework provides the overall structure and calls your code (inversion of control).

Library	Framework
You call library functions	Framework calls your functions
You control program flow	Framework controls program flow
Add features to your code	You build within the framework
Example: jQuery, Lodash	Example: Vue.js, React, Angular

Frameworks provide a "skeleton" - you fill in the specific parts for your application.

Why Vue (official intro) — the framework's own pitch: declarative rendering + reactivity vs. hand-written DOM code.
