1 : Are the Dart programs faster? At a glance.
Each chart bar shows, for one unidentified benchmark, how much the fastest Dart program used compared to the fastest Scala program.
These are not the only compilers and interpreters. These are not the only programs that could be written. These are not the only tasks that could be solved. These are just 10 tiny examples.
2 : Are the Dart programs faster? Approximately.
Each table row shows, for one named benchmark, how much the fastest Dart program used compared to the fastest Scala program.

3 : Are the Dart programs faster? Measurements.
These are not the only tasks that could be solved. These are just 10 tiny examples. These are not the only compilers and interpreters. These are not the only programs that could be written.
For each named benchmark, measurements of the fastest Dart program are shown for comparison against measurements of the fastest Scala program.

4 : Are there other Dart programs for these benchmarks?
Remember - those are just the fastest Dart and Scala programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Dart.
Maybe one of those other Dart programs is fastest on a different OS/machine.
