Translation guide
A program that converts code into machine language at runtime, rather than ahead of time. In Japanese, the English term is widely used, often abbreviated as JITコンパイラ.
The standard term for a just-in-time compiler in computing.
The most common and natural way to refer to a just-in-time compiler in Japanese. 'JIT' is pronounced as an initialism.
この言語処理系はJITコンパイラを搭載している。
This language implementation includes a JIT compiler.
A direct transliteration of the full English term. Rarely used; JITコンパイラ is strongly preferred.
ジャストインタイムコンパイラは起動時間を短縮できる。
A just-in-time compiler can reduce startup time.
In Japanese technical writing and conversation, 'JITコンパイラ' is the default. Using the full transliteration 'ジャストインタイムコンパイラ' may sound overly literal or pedantic.
A more descriptive Japanese term meaning 'runtime compiler'. Less common than JITコンパイラ but fully understandable.
実行時コンパイラによってパフォーマンスが向上する。
Performance improves with a runtime compiler.
