Mentors demo

The Mentors demo is an in-session demo for forEach, map, filter, and chained filter. Use index.js to implement the TODOs in class (FOREACH, MAP, FILTER, CHAINING). The README describes the files, how tasks are marked, and how the code works. index-solution.js has the full implementation for reference.

Session Outline

Array functions

Write this code with traditional functions, no arrow functions yet!

• Try to write your own forEach, map and filter with the trainees. Shows very precisely how it works!

• forEach - Executes function for each item in the array, NO RETURN!

  • Mentors demo – do FOREACH TODO

  • Code inspiration

  • forEach homemade

  • Exercises

• map - Changes/transforms the items in the array

  • Mentors demo – do MAP TODO

  • Code inspiration

  • map homemade

  • Exercises

• filter - Changes the number of items in the array. Let the trainees investigate filter

  • Mentors demo – do FILTER TODO

  • Code inspiration

  • filter homemade - Get help from trainees to write this

  • Exercises

• Mentors demo – do CHAINING TODO (multiple filter conditions)
