TIL 2020-09-03

  1. ReactJS docs with hooks - Converting React class components to use hooks for better code organization.

  2. Regex101 - Online regex tester and debugger with explanations.

  3. Regexr - Interactive regular expression tool for learning and testing.

  4. Pandas Performance Tip - It’s much faster to use Pandas’ filters with the & and | operators than combining conditions with zip. Use intermediate dataframes and multiple .loc calls instead of zip with any or all.
