Format a label

YOUR TASK

Make this happen

3 steps

  1. string.format combines a format string and typed arguments. Produce a label with a name, a colon and an integer count.

  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

exports.label = function(name: string, count: number): string
  return name
end

lesson.test.lua

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

t.it("label includes count", function()
  local s = subject.load()
  t.expect(s.label("Paper", 12)):eq("Paper: 12")
end)
