The Lively Kernel is an open-source web programming environment, developed by Dan Ingalls when he was at SAP Research. It supports desktop-style applications with rich graphics and direct manipulation abilities, but without the installation or upgrade troubles of conventional desktop applications.

Access to Methods and Properties of Internal Objects: TestComplete reads the names of the visible elements and many internal elements of Delphi, C++Builder, .NET, WPF, Java and Visual Basic applications and allows test scripts to access these values for verification or use in tests.
To prevent an event from bubbling, developers must call the stopPropagation() method of the event object. To prevent the default action of the event to be called, developers must call the preventDefault() method of the event object. The main difference from the traditional model is that multiple event handlers can be registered for the same event.
Dynamic websites sometimes use custom web application servers, such as Glassfish, Plack and Python's "Base HTTP Server" library, although some may not consider this to be server-side scripting. When using dynamic web-based scripting techniques, developers must have a keen understanding of the logical, temporal, and physical separation between ...
Transpilation is a source-to-source compilation in which newer versions of JavaScript are used, and a transpiler rewrites the source code so that it is supported by older browsers. Usually, transpilers transpile down to ES3 to maintain compatibility with all versions of browsers.
Google created V8 for its Chrome browser, and both were first released in 2008. [4] The lead developer of V8 was Lars Bak, and it was named after the powerful car engine. [5] For several years, Chrome was faster than other browsers at executing JavaScript. [6] [7] [8] The V8 assembler is based on the Strongtalk assembler. [9]
