QuickJS to be Updated

French mathematician Fabrice Bellard, who once founded the QEMU and FFmpeg projects, has published an update to the QuickJS compact embedded JavaScript engine he is developing. The engine supports the ES2019 specification and additional mathematical extensions, such as the BigInt and BigFloat types. In performance, QuickJS is noticeably superior to its existing counterparts (XS by 35%, DukTape more than twice, JerryScript three times, and MuJS seven times). The project offers a library for embedding the engine, a qjs interpreter for running JavaScript code from the command line, and a qjsc compiler for generating self-contained executable files. The code is written in C and distributed under the MIT license. More details about the project can be found in the text of the announcement of the first issue.

The new version adds experimental support of the BigDecimal type, which allows you to manipulate decimal numbers with arbitrary precision (analogue of BigInt for numbers with base 10). Updated implementation of operator overloading. Added examples of programs for effectively calculating the Pi number up to a billion decimal places (as a mathematician, Fabrice Bellar is known as the creator of the fastest formula for calculating the Pi number).
