In 3.0, Scratch blocks are implemented using Blockly, a JavaScript library developed by Google for creating block-based visual programming languages. [ 45 ] [ 46 ] On 13 May 2014, a year after the release of Scratch 2.0, it was announced by a developer on the Scratch Forums that 2.0 would become open source.
Extended sets of blocks can be found in Snap! libraries, such as the 'streams' library that enables one to make the complete, infinite Fibonacci sequence, for example, using the special blocks ('stream', 'show stream', 'tail of stream', and 'map ( ) over stream' block) from the library.
mBlock 3 is a block-based programming software based on Scratch 2.0. It interacts with Makeblock controller boards and other Arduino-based hardware, allowing users to create interactive hardware applications. The block-based code can be converted to Arduino C and supports various operating systems including macOS, Windows, Linux, and Chromebook ...

An important use is when a left-associative binary operator modifies its left argument (or produces a side effect) and then evaluates to that argument as an l-value. [a] This allows a sequence of operators all affecting the original argument, allowing a fluent interface, similar to method cascading.

For example, if A = {1,2,3,4}, where the components are x, y, z, and w respectively, you could compute B = A.wwxy, whereupon B would equal {4,4,1,2}. Additionally, one could create a two-dimensional vector with A.wx or a five-dimensional vector with A.xyzwx. Combining vectors and swizzling can be employed in various ways.
It recently yielded around 3.5% and it held stock in roughly 100 companies. Buying into a good dividend-focused ETF can save you from having to research and pick individual dividend payers, hoping ...
