| ## Why? | ||
| - Born out of a real need | ||
| - Alternative to writing a lot of custom code for transforming collections of JSON objects | ||
| - Quick validation of MongoDB queries without the need for a database | ||
| - MongoDB query language is among the best in the market and is well documented | ||
| - Finally, because queries are better than me and perhaps you too :) | ||

Major refactor

Found 1 instance in 1 package
Uses eval
Supply chain riskPackage uses dynamic code execution (e.g., eval()), which is a dangerous practice. This can prevent the code from running in certain environments and increases the risk that the code may contain exploits or malicious behavior.

Minified code
QualityThis package contains minified code. This may be harmless in some cases where minified code is included in packaged libraries, however packages on npm should not minify code.
