Scratch takes its name from a technique used by disk jockeys called "scratching", where vinyl records are clipped together and manipulated on a turntable to produce different sound effects and music. Like scratching, the website lets users mix together different media (including graphics, sound, and other programs) in creative ways by creating and 'remixing' projects, like video games, animations, music, and simulations.[8][9]

Scratch uses event-driven programming with multiple active objects called sprites.[10] Sprites can be drawn, as vector or bitmap graphics, from scratch in a simple editor that is part of Scratch, or can be imported from external sources. Scratch 3.0 only supports one-dimensional arrays, known as "lists", and floating-point scalars and strings are supported, but with limited string manipulation ability. There is a strong contrast between the powerful multimedia functions and multi-threaded programming style and the rather limited scope of the Scratch programming language.
There are three pathways into ScratchX. If you have been given or sent a .sbx file, you can load that into ScratchX via the homepage (look for 'Open an Extension Project'). If you have been sent a ScratchX URL (starts with 'scratchx.org/'), you can click your link and the extension will load automatically, or you can enter that URL into the box on the homepage (look for 'Open an Extension URL'). Lastly, if you don't have an example extension, you can try out one on the site by visiting the Gallery page and clicking on an example extension there.
A program is software containing a series of coded instructions to control the operation of an electronic device (noun), and the activity of creating coded instructions in support of a particular task of an electronic device (verb). Programs are created using a programming language that includes rules and a system of symbols. The language must conform to these rules of syntax and semantics, but unlike many commonly used physical electronics, they often are not created as part of a standards body. A programming language may be developed from scratch, but more often are built within a programming family, using previous programming languages as a base starting point, and may rely on another programming language to effectively function on a machine.
