JavaScript 30 — Day 7 - Array Cardio 2

I went back to visit family over the weekend and I fell behind a little with both the coding and my documentation of the challenge.

The purpose of this challenge, for me, was not designed for stringent daily practice but rather a good guideline of what is easily digestible in daily increments.

In any case, I am back and have a backlog to share.

This day’s exercise was relatively uneventful but nevertheless useful. As a sequel to Day 4’s Array Cardio session, it dives into a few more Array methods:

• some
  - some() is a handy method that will return a boolean value True if the condition is met for any of the array elements
• every
  - every() on the other hand is similar to some() but, you guessed it, only returns True if the condition is met for ALL the array elements
• find
  - I like to think of find() as like a singular use of filter(). Find () will return the first element that that satisfies the condition.
  - However these two aren’t exact comparisons since filter() will still return an array even with just one element in it if that is the case.
• findIndex
  - Just like find() but it returns the index of the element rather than the element itself.
