This package contains utilities for generating optimized JavaScript code at runtime. It enables creating high-performance functions by generating code dynamically based on schemas, templates, or runtime data.
JIT (Just-In-Time) code generation can provide significant performance improvements when you have advance knowledge of the data structure or execution pattern.
Some examples:
-
Deep equality comparison function: When one object is known in advance, we can generate an optimized function that efficiently compares against a single object. This technique is implemented in the
json-equallibrary. -
JSON Patch execution: When the JSON Patch operations are known beforehand, we can generate an optimized function that applies the patch in the most efficient way. This approach is used in the
json-patchlibrary. -
Schema-based validation: Given a
json-typeschema of a JSON object, it's possible to generate highly optimized functions for validation and serialization that avoid generic overhead and execute significantly faster than traditional approaches.
