Fundamental JS – May 23rd – Array Methods talk

I’m giving a talk tomorrow night (May 23rd) at Fundamental JS on Array methods.  Check out the Fundamental JS Meetup Site for details.  I will cover the following:


  • What is an array?
  • What is a prototype?
  • I will review four array methods
    • map()
    • forEach()
    • reduce()
    • filter()
  • I will then show how create these methods from scratch and add them to the Array.prototype


This is a link to my slides for the talk, and a github repo with the code and some other links:
