All programs are made up of statements, and each statement is an instruction to the computer about something we need it to do. A great way to come up with fresh ideas for future projects. Here’s how we create a variable named score in JavaScript: var score 0 That line of code is called a statement. There are often Scratch Design Studio challenges, which encourage students to compete.Įducators have their own ScratchEd community in which they can share stories and resources as well as ask questions. Code efficiency: Code efficiency is a broad term used to depict the reliability, speed and programming methodology used in developing codes for an application. Members on the site can comment, tag, favorite, and share the projects of others. 5 Scratch's primitive data types are numbers, strings and Booleans. Scratch is dynamically-typed, meaning that whether data types agree is checked during program execution. Since Scratch is so widely used, there are lots of interactivity opportunities. Scratch is a block-based imperative, event-driven, dynamically-typed and interpreted programming language. The online community is another powerful feature. Students can get a fun and exciting result relatively easily, encouraging future use and more in-depth exploration of coding. The biggest appeal of Scratch is its ease of use. Want to build a real world robot and have it dance? This will let you code the movement part. That said, Scratch does work with lots of other real-world projects such as LEGO Mindstorms EV3 and BBC Micro:bit, allowing for greater outcome potential from the coding platform. All of our content is peer reviewed and validated by. It's a very basic version of coding, which teaches students more the process of action event-based coding rather than the deep language itself. authors are vetted experts in their fields and write on topics in which they have demonstrated experience. And different programming languages that each have their own set of rules. There are various types of different code, depending on what you want to develop. Coding allows us to create things such as computer software, websites, apps and video games. So a cat cartoon could be made to walk forward 10 steps, for example. Put simply, Coding is the a method of communicating with a computer. A sprite character can be selected, and commands can be dragged from the block palette area into the coding area that allows the actions to be carried out by the sprite.
