Tested on:

• Processor: AMD Ryzen 7 Microsoft Surface (R) Edition 2.00 GHz
• Installed RAM: 16.0 GB
• System type: 64-bit operating system, x64-based processor
• polars version: 0.0.6

Basic list operation

Polars series was compared against

• native array methods
• lodash
• ramda

The tests were run 100 times each to get the results
