Keep state local

YOUR TASK

Make this happen

3 steps

  1. A local variable belongs to its lexical scope. Update a local accumulator before exporting its value. This prevents accidental global names and makes the calculation easy to follow.

  2. Read the cases in lesson.test.lua, then choose Check solution to see what needs to change.

  3. Update subject.lua until every test passes. Keep the supplied tests unchanged.

Start with Check solution, then use the failures to guide your edits.

Read the starter and tests

subject.lua

local count = 2
exports.count = count

lesson.test.lua

local t = require("test")
local subject = require("cococo.subject")

t.it("adds three", function()
  local s = subject.load()
  t.expect(s.count):eq(5)
end)
