Build a greeting

YOUR TASK

Make this happen

3 steps

  1. Lua joins strings with two dots. Keep the separator inside a string so the greeting has a space before the name.

  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.greet = function(name: string): string
  return name
end

lesson.test.lua

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

t.it("greets Ada", function()
  local s = subject.load()
  t.expect(s.greet("Ada")):eq("Hello, Ada")
end)

t.it("greets another person", function()
  local s = subject.load()
  t.expect(s.greet("Lin")):eq("Hello, Lin")
end)
