Start of Analyzer for Bird Watcher

[pertrai1]

Based on the below from design doc - https://github.com/exercism/javascript/blob/main/exercises/concept/bird-watcher/.meta/design.md

---

• For all tasks check that the student actually used a for loop.

totalBirdCount

• Verify that the condition is written with < x.length instead of <= y.length -1.
• Check whether a shorthand assignment += was used to increase the sum (non-essential feedback).
• Verify the total was properly initialized with 0 instead of e.g. null
• Verify the increment operator was used in loop header step

birdsInWeek

• Verify a helper variable was used instead of duplicating the calculation in the initialization and condition of the loop
• Other checks should be the same as for totalBirdCount

fixBirdCountLog

• Check that no if-statement was used (it is not necessary if the step size was set correctly), type actionable
• Check whether a shorthand assignment += was used to increase the loop counter (non-essential feedback)
• Check whether the increment operator was used in the loop body

---

• modify index.ts for output
• create custom comments where needed

@pertrai1 FYI I added one item to the list for the last task that I saw a lot recently in mentoring.
