Luau Core Language

When to Load

Load for Luau semantics and JS/Python translation. Types: roblox-luau-types; lifecycle: roblox-luau-patterns; engine APIs: domain skills.

Quick Reference

Only false and nil are falsy. 0, "", and {} are truthy.
Equality does not coerce types. 0 == "0" is false. Inequality is ~=.
Array conventions are 1-based. #array is meaningful only for a sequence without nil gaps.
Assigning nil removes a table key; assigning a table copies the reference; table.clone is shallow.
Dictionary iteration order is unspecified. Do not make behavior depend on it.
Dynamic keys require brackets: record[field]. Dot syntax uses a literal identifier.
Missing arguments become nil; extra results and arguments can be discarded.
Prefer an if expression over condition and a or b when a may be falsy.
Locals start at their declaration; repeat locals reach until. Forward-declare mutual recursion.
Luau string patterns are not regular expressions. Their syntax and capabilities differ.
Backtick interpolation and .. are valid. Join many fragments once in hot loops.
NaN does not equal itself and defeats </>; test with x ~= x.
Binary data uses the buffer library: fixed size, 0-based offsets, explicit-width reads/writes. Avoid buffer.readinteger/writeinteger (stubs, not released runtime).
For Base64, hashing, or compression use EncodingService (buffers, not strings; JSON via HttpService). Details: see full reference.

luau

local label = if enabled then "On" else "Off"
local message = `{name}: {score}`

local byId: {[number]: string} = {}
byId[userId] = name

for index, value in values do
    print(index, value)
end

Translation traps

JavaScript ===, !==, null, optional chaining, spread, arrow functions, and array methods are not Luau syntax.
Python None, zero-based list assumptions, list comprehensions, exceptions, and implicit tuple behavior do not translate directly.
x or fallback tests truthiness, not only absence. It replaces a valid false value.
typeof(value) recognizes Roblox datatypes; type(value) reports the underlying Luau type category.
