OPTIMIZING RUBY'S JSON, PART 4

Summary from the TLDR Web Dev newsletter

The author, a recent maintainer of Ruby's `json` gem, made it the fastest JSON parser and generator in many benchmarks. These improvements weren't complex; they involved straightforward optimizations identified through profiling, showing that simple changes can yield substantial speed gains. The motivation stemmed from the widespread, albeit problematic, use of the faster-but-less-reliable `oj` gem, which caused compatibility issues and crashes due to its aggressive monkey patching and less robust coding practices.
