importArticles — Best Practices for installing JavaScript on FANDOM
The importArticles statement is designed to combine multiple HTTP requests into a single data transfer, allowing multiple scripts to load and execute faster. If you've been installing several different scripts, your JavaScript file has probably accumulated unnecessary import statements. Click "Expand" to learn how to efficiently batch import scripts to speed up performance and make your code look cleaner. One other approach is by using the MediaWiki:ImportJS.
If your JavaScript file has several lines of code that say importScript, importScriptPage, or importArticles, you may be able to combine them! By batch importing a collection of scripts with a single import, your JavaScript code will load faster and look cleaner. Consider the example below. On the left is an example of what your JavaScript file might currently look like. On the right is how you could improve that code.
Multiple imports — messy and slow One import — clean and efficient
  type: 'script',

importScriptPage('page1.js', 'wikiname');
importScriptPage('page2.js', 'wikiname');

Note: In this example, pay close attention to the placement of commas and other punctuation. For people who aren't familiar with programming (and even those who are!), a common mistake when writing code is to accidentally delete, forget, or misplace critical symbols like commas or quotation marks. This can cause a syntax error that breaks the code. Carefully follow the convention shown here when using importArticles.
But there's much more to importArticles than just this! For more examples and advanced usage, see the help page at Help:Including additional JavaScript and CSS.

Note: When you use the script for the first time, refresh the page, or cleared the cache, it will take a while to load all external scripts.

Once the script is installed, when browsing a JavaScript or CSS code page, a "View code" button will appear. Clicking the button will change the appearance of the code. The number of pages of the wiki will change into the number of characters of the code.

To edit the code, click on the "Edit" button.

To publish the code, click on the "Publish" button. Beside the button is a drop-down arrow. Clicking the arrow will open a drop-down menu. The options in the menu are "Shortcuts," "Show changes," and "Save."

Clicking the "Shortcuts" option will open a popup that displays the following:

Alt → Go to last character of selected line
Alt ← Go to first character of selected line
Alt L Go to line
Ctrl [ Indent less
Ctrl ] Indent more
Ctrl B Beautify
Ctrl D Remove line
Ctrl F Search
Ctrl G Find next
Ctrl M[1] Minify
Ctrl Space[2] Open hints
F11 Go to (or exit from) full screen mode
Shift Ctrl F Replace
Shift Ctrl G Find previous
Shift Ctrl R Replace all

Clicking the "Show changes" option will open a popup that displays the changes you made in the code.

Clicking the "Save" option will store the code in your browser using localStorage. To continue where you left off, click the "Load" option. These options are browser-dependent (i.e., if you saved a code in browser X, you can load that saved code in that browser only).

  1. Three buttons will appear: one for selecting the minified code, one for transferring the minified code to the code editor, and the other for publishing a page that contains the minified code.
  2. A popup menu will appear. It displays auto-completion suggestions, as well as the list of variable names, functions, and methods.
