Project: The Task Shape

Part of the Introduction To Luau section of Coddy's Lua journey — lesson 45 of 73.

Challenge

Easy

Lay the foundation of the task manager.

Define a type alias named Task describing a table with:

id of type number
title of type string
done of type boolean

Create a typed array named tasks of type {Task} containing, in order:

id 1, title "Learn Luau types", done false
id 2, title "Build a task manager", done false
id 3, title "Write tests", done true

Then print, each on its own line:

the first task's id
the first task's title
the first task's done flag
how many tasks there are (use #)

Try it yourself

-- Write code here
-- 1) define type Task = {id: number, title: string, done: boolean}
-- 2) create tasks: {Task} with the three starter tasks
-- 3) print the first task's id, title and done flag, then the task count
