DEFINTIONS:
AppleScript
AppleScript is a mature scripting language developed by Apple. Its relatively easy to learn in relation to other scripting and programming languages, has been around since System 7.1, and has been widely adopted in both enterprise and personal workflows. While the AppleScript scripting language uses an English-like terminology which may appear simple, it is a rich, object-oriented language, capable of performing complicated programming tasks.
JavaScript
JavaScript is a popular cross-platform scripting language. Historically, its been most commonly used to implement features on websites and in web-based apps that are accessed through browsers. However, some apps implement JavaScript-based scripting models for the purpose of automation. In OSX 10.10, JavaScript became a peer to AppleScript in OSX. There are many third-party websites and books that document the JavaScript language.
