Summary: And, btw, the tests show that performance of that is not so great: ``` Running /Users/shergin/fbsource/fbobjc/buck-out/cells/fbsource/gen/xplat/js/react-native-github/ReactCommon/fabric/core/benchmarks Run on (12 X 2900 MHz CPU s) CPU Caches: L1 Data 32K (x6) L1 Instruction 32K (x6) L2 Unified 262K (x6) L3 Unified 12582K (x1) -------------------------------------------------------------------------------------------- Benchmark Time CPU Iterations -------------------------------------------------------------------------------------------- propParsingUsingComponentDescriptor 79630 ns 77991 ns 8864 propParsingUsingComponentDescriptorWithNoSourceProps 70200 ns 69099 ns 8362 ``` Which means 70ms per 1000 prop parsing processes.
