Key Atụmatụ:
- Mpempe akwụkwọ nke nta nke nta, na-anọ n'ọnọdụ etiti n'etiti mpịpị siri ike na kwụ ọtọ. Luau na-enye gị ohere iji mpịnye static dị ka achọrọ site na ịkọwa ụdị ozi site na nkọwa pụrụ iche. Ụdị arụnyere n'ime ya bụ "ọ bụla", "nil", "boolean", "nọmba", "eriri" na "eriri". N'otu oge ahụ, a na-echekwa ohere nke iji mpịnye dị ike na-akọwapụtaghị nke ọma ụdị mgbanwe na ọrụ. ọrụ foo(x: nọmba, y: eriri): boolean mpaghara k: eriri = y: rep(x) nloghachi k == "a" njedebe
- Nkwado maka mkpụrụedemede nkịtị (dịka na Lua 5.3) dị ka "\0x**" (nọmba hexadecimal), "\u{**}" (Unicode character) na "\z" (njedebe ahịrị), yana ike iji anya nke uche hụ nhazi nọmba (ị nwere ike dee 1_000_000 kama 1000000), mkpụrụedemede maka hexadecimal (0x...) na ọnụọgụ abụọ (0b......).
- Nkwado maka okwu "gaa n'ihu", na-emeju isiokwu "nkwụsị" dị ugbu a, ka ịwụba na ntinye aka ọhụrụ.
- Nkwado maka ndị na-arụ ọrụ nhazi (+=, -=, *=, /=,%=, ^=, ..=).
- Nkwado maka ojiji nke ọnọdụ "ọ bụrụ-mgbe ahụ-ọzọ" ngọngọ n'ụdị okwu na-eweghachi uru gbakọrọ n'oge ogbugbu nke ngọngọ. Ị nwere ike ezipụta ọnụ ọgụgụ aka ike nke okwu ndị ọzọ na ngọngọ. local maxValue = ma ọ bụrụ na a > b wee bụrụ akara ọzọ b akara mpaghara = ma ọ bụrụ x 0 wee 1 ọzọ 0
