Flutter Java

JIT (Just in Time) compiles at runtime on-the-fly while AOT (Ahead of Time) compiles before the application is deployed and launched . A program written in Swift is different from a program written in Kotlin.

JIT downloads the compiler and compiles code exactly before Displaying in the browser . AOT has already complied with the code while building your application, so it doesn’t have to compile at runtime. Loading in JIT is slower than the AOT because it needs to compile your application at runtime.

Just-in-Time (JIT) is a type of compilation that compiles your app in the browser at runtime. Ahead-of-Time (AOT) is a type of compilation that compiles your app at build time.

Dart runtimes and compilers support the combination of two critical features for Flutter: a JIT-based fast development cycle that allows for shape changing and stateful hot reloads in a language with types, plus an Ahead-of-Time compiler that emits efficient ARM code for fast startup and predictable performance of …

The Angular ahead-of-time (AOT) compiler converts your Angular HTML and TypeScript code into efficient JavaScript code during the build phase before the browser downloads and runs that code. Compiling your application during the build process provides a faster rendering in the browser .

Static Compilation: Statically compiled programs are all translated into machine code before execution. Ex: AOT(Ahead of Time ) – C/C++. Dynamic Interpretation: is executed by one-to-one translation. Ex: JIT(Just in Time) – Javascript/Python.1 Kas 2020

The AOT-compiled code runs inside an efficient Dart runtime that enforces the sound Dart type system and manages memory using fast object allocation and a generational garbage collector.
