JavaScript[1] is
| “ | a general purpose, cross-platform scripting language, whose code can be embedded within standard Web pages to create interactive documents.[2] | ” |
Overview[]
"Within the context of the Web browser, JavaScript is extremely powerful, allowing prepared scripts to perform essentially the same actions as those a user could take. Within that context, JavaScript lacks methods for directly accessing a client file system or for directly opening connections to computers other than the host that provided the content source. The browser also normally confines a script’s execution to the page from which it was downloaded."[3]
