Let’s practice

Exercises

• Create a function reverseArray which would reverse array and return it as a result
• You’ve given an array of teachers and you need to create a function which would iterate over it and return a string with all teachers names divided with ,. Then do the same but usign forEach.
• Create a function summation(n) that takes a single argument n, and computes the sum of all integers up to n starting from 0:

  summation(3) -> 1 + 2 + 3 = 6
  summation(7) -> 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28
  

• Create a small form with following fields: Name, Surname, Email address and Age. After user clicks “Submit” button please console log the object with complete user data.

Bonus exercise

Build a “TO-DO list”. That’s it :) Should be possible to add Todo items and remove then. Simple but nice to use.
