Scratch is a block-based visual programming language and vector/raster graphics editor for children designed to create things such as games, animations, art, and stories. It allows them to explore and experiment with the ideas of computer programming by using "blocks" that are put together to make simple code. There is also a discussion page with multiple forums mainly used for chatting and help with coding.

Although made for children 8-16, Scratch can be used to produce simple or complex programs. Some notable users who push the boundaries of what scratch can do include: Griffpatch, -Myths-, TimMcCool, Will_Wam, and World_Languages.

Scratch is translated into 40+ languages and is used in homes, schools, and after-school clubs in nearly every country in the world. Scratch is often used in teaching coding, computer science, and computational thinking. Teachers also use it as a tool across many other subjects, including math, science, history, geography, and art. The Scratch Team is an organization that helps maintain, manage, and help keep Scratch safe. They also do helpful tutorials for coding help and support. Scratch is free to use.

Test Scratch Wiki

Test Scratch Wiki

The Test Scratch Wiki is a collaborative, multilingual platform created to support the development of new language editions of the Scratch Wiki. It is managed by the international Scratch community and provides a space where Scratch users, known as Scratchers, can begin building and maintaining wiki articles in their native languages before they are promoted to full, standalone wikis.

Purpose

The primary purpose of the Test Scratch Wiki is to encourage knowledge sharing and localization of educational resources related to Scratch, a block-based programming language and online community developed by the MIT Media Lab. By providing a testing ground, it allows contributors to:

• Translate and adapt existing articles
• Create new content relevant to their cultural and educational context
• Collaborate with other users to ensure content quality and accuracy

Once a language section becomes active with a growing number of high-quality articles and committed contributors, it may become eligible to launch as an official language-specific Scratch Wiki.

Features

• Multilingual Support: Contributors from around the world can work in over a dozen languages.
• Scratch-Focused Content: Articles include tutorials, programming techniques, Scratch history, and community guidelines.
• Volunteer Driven: Managed entirely by Scratch community members, it is a grassroots effort promoting global inclusivity in computing education.

Hindi Scratch Wiki

The Hindi Scratch Wiki is a prominent subproject of the Test Scratch Wiki, dedicated to creating Hindi-language content about Scratch programming. It has become one of the most active language sections on the platform, aiming to make Scratch accessible to Hindi-speaking students, educators, and enthusiasts.

Notable Editors

• StarGold- The recognized leader of the Hindi Scratch Wiki, StarGold- played a pivotal role in establishing the structure, editorial guidelines, and initial content. Under their leadership, the Hindi section gained momentum and community involvement, helping it emerge as one of the top contenders for future full-language wiki status.
• RAMANRANJAN2282 is an active contributor to the Hindi Scratch Wiki, noted for their involvement in article development, formatting, and community support.
• The team of Hindi Scratch Wiki Consist of More 8 member.https://scratch.mit.edu/discuss/topic/807046/?page=1#post-8403104

The area where the user can interact is called the stage area. The stage area features all of the animations, graphics, drawings, and other visual features. The list of sprites on screen are placed below the stage area to show a list of sprites that are usable for the program. The stage is organized through x and y coordinates, with the center coordinate (0, 0) in the center of the stage. The stage is 480 pixels wide and 360 pixels tall, with a range between x=-240 to x=240 in width and a range between y=-180 and y=180 in height.

From left to right, in the upper left area of the screen, there is a stage area, featuring the results (i.e., animations, turtle graphics, etc., everything either in small or normal size, full-screen also available) and all sprites thumbnails listed in the bottom area. The stage uses x and y coordinates, with 0,0 being the stage center. The stage is 480 pixels wide, and 360 pixels tall, x:240 being the far right, x:-240 being the far left, y:180 being the top, and y:-180 being the bottom.

Category		Notes		Category		Notes
	Motion	Moves sprites and changes angles and change X and Y values.			Events	Contains event handlers that are placed on the top of each group of blocks to start a programme or start to make something happen.
	Looks	Controls the visuals of the sprite. The sprite may be attached a speech bubble or a thought bubble, the background or sprite can be changed, it can be enlarged or shrunken, it can have transparency, or it can have shading.			Control	Contains conditional if-else statements, as well as conditional statements "forever", "repeat", and "stop".
	Sound	Plays sound files and allows the programming of a musical sequence.			Sensing	These tools are used for directing sprites to interact with the surroundings that the user has created.
	My Blocks	Allows you to make your own blocks.			Operators	Mathematical operators, random number generator, and-or statement that compares sprite positions
	Data	Deals with declaring variables and lists, as well as for adjusting variables and lists.			Extensions	Custom procedures (blocks) and external devices control and can import from PicoBoard or Lego WeDo 1.0/2.0
