Scratch

  • Scratch electrical and electronic kits:


    Development roadmap:

    The 1.4, 2.0 and 3.0 software versions of scratch are developed with Smalltalk, flash and HTML5 respectively.


    Scratch 1. X period

    Scratch 1. X is written in Smalltalk. As part of the project "one laptop per child", Smalltalk proposes a suggested language learning sequence, in which each language is designed as the introduction and foundation of the next one. The order is: scratch eToys squeak any Smalltalk. In the process of learning, each language provides a graphical programming environment, which is not only used to teach children some programming concepts, but also some exercises including simulation and story telling of physical and mathematical knowledge. Smalltalk and squeak, as full-featured application development languages, have become very famous in the past decades, and scratch is a tool for children to learn. Throughout 1 In the X series, scratch's official website remains basically unchanged. This version of scratch has no connection with the website (except the publisher). This has changed in the 2.0 period. People can make programs in web pages.electronic parts from scratch 


    Scratch 2.0 period

    Scratch 2.0 was announced by andresmh at the scratch forum in January 2010. It is written in flash. Vector graph is supported. It is divided into offline version and online version. The online version allows you to create, edit and view projects directly in the web browser (there is no need to upload, Download projects or install other software), and you can use cloud variables. The offline version can only make programs locally and cannot use cloud variables. [7]

    Scratch2. 0 offline version is available for download on the official website of scratch, which is easy to use when you can't connect to the Internet. Version 2.0 strengthens the interaction with external linked devices, such as LEGO wedo, etc. 2020 is replaced with more advanced version 3.0, and scratch2 is no longer available on the official website 0 editor.


    Scratch 3.0 period

    Scratch 3.0 abandons flash and uses HTML5. HTML5 is the sum of the latest HTML, CSS and JavaScript. Scratch 3.0 will first use webgl, web workers and web audio JavaScript libraries. JavaScript is a broad language that supports all browsers and webgl for cross platform use. It has been carefully selected, and JavaScript does not require any additional plug-ins to run.

    The name scratch 3.0 was first proposed by Andrew Sliwinski of the scratch team in May 2016. In January 2018, the first public beta version of scratch 3.0 (scratch 3 beta) was released on the official website of scratch, the release version of scratch 3.0 online editor was released in January 2019, and the offline editor is also available for download after January 2019.

    Scratch 3.0 is not only refactoring, but also adding some functions, such as string inclusion judgment, moving to the lowest building block, etc. The shape of the editor looks more soft, dragging blocks and sound effects, and supports multiple withdrawals and restores. The file format saved by scratch 3.0 is Sb3, can be read Sb and SB2 file.


    ScratchJR

    Scratchjr of MIT is a tablet application specially developed for preschool children in the scratch programming language, which is suitable for children aged 5-7 to learn programming.
