• calculate average of 3 variables

let v1=43242;
let v2=234;
let v3=4534;

• now make that result is float instead of integer

• create function that can calculate average of 3 arguments

• print some list, does it look different than you expected? Is is different than array? Can you convert list to array?

• Did you find out function Js.log2, Js.log3 try to use them.

• make some arguments of average function named

• make 2. argument optional

• generalize avarage function to take list

• change average function to take array

• return from average tupple representing average and number of elements

• Declare some optional value and print it with switch. Then instead of switch try to use Belt.Option.getWithDefault

• find out how to define recursive functions and create ternary fibonaci F_n = F_(n-1) + F_(n-2) + F_(n-3)

• create pokemon record: pokemon has name, height and mutlityple types(Electric,Water,...) modeled for begging as array of string (word type is reserved so its better to name that field as kind or if you like suffering _type, type_)

• try to print one pokemon does it look as you expected? What about when you try to use js obejcts(use apostrophs)

{
 "name": ...,
}

• change pokemon kinds(types) to variants

• define some array of pokemons(or google them) this will be our data to work on

• Print only water type of pokemons

• When printing don't relly on special Js.log smemantics but create strings from pokeomon and print only strings. (how do you convert variant to string?)

• put pokemon record definition and helper function into separate module.

• by convenience Pokemon module should have name record of pokemon as t, and expose make function.

module Pokemon = {
  type t = {
  }
  let make= (~name, ...):t => {
  }
  let to_string = (pokemon: t) =>
}

• compare how this pokemon module looks to Js.Date module.

• try to use Js.Date module and what it actualy compiled as output

• PRO make last argument of average function optional and fix errors (remember unit as last example)

• PRO find out how to patterm match with switch on list variable when average function taked list as argument

• PRO-PRO make two functions that recursivly call each other
