The repository is a fork of https://github.com/KvanTTT/AntlrBenchmarks to measure the perfomance loss of the antlr parsers in Javascript relative to Java ones, from antlr 4.8 to antlr 4.13.
Install Powershell and run the script ./benchmark.ps1 in Benchmark directory
For antlr 4.8:

| JavaStandard_LeftRecursion | 211838 | 1.24 |
| JavaScriptStandard_LeftRecursion | 736566 | 4.30 |
For antlr 4.13:
| Runtime | Mean [ns] | Ratio |
|---|---|---|
