Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux, Unix, macOS, and more. Node.js runs on the V8 JavaScript engine, and executes JavaScript code outside a web browser . Node.js lets developers use JavaScript to write command line tools and for server-side scripting.
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...
Paste the URL into the box. (The code will automatically generate.) Edit. Click on the QR code image and save it. Import the QR code image into a word processor programme or graphics package. (Optionally) Add text labels. Print. Print the code a minimum of 1 inch (2.5 cm) across, where possible 2 inches (5 cm).

Date: 9 April 2013: Source: This file was derived from: QR Code Structure Example 2.svg: Author: Bobmath: Other versions: This is a modified version of QR Code Structure Example 2.svg, as the QR code in that image is too small and does not actually contain version information.
To do so technically would require a more sophisticated grammar, like a Chomsky Type 1 grammar, also termed a context-sensitive grammar. However, parser generators for context-free grammars often support the ability for user-written code to introduce limited amounts of context-sensitivity. (For example, upon encountering a variable declaration ...
