=== JavaScript & user scripts ===
{{main|Wikipedia:User scripts}}
On Wikipedia, JavaScript can be used to add new features such as add find/replace textboxes or give advanced rollback options. There are scripts to customise everything, from default font style to custom buttons.

Many script pages can be [[Template:Js|imported and used]]. Different scripts can also be used in conjunction with each other to accomplish several tasks at once. Some scripts are available as "Gadgets", which means they can be installed by simply ticking a box in the "Gadgets" tab of [[Special:Preferences]].

In order to add pre-existing scripts to your JavaScript page, add <code><nowiki>{{subst:js|name of script}}</nowiki></code> to the file. More detailed instructions can be found at the [[Wikipedia:User scripts/Guide]].
