Just In Time Compilers

Just in time compilers are compilers that do compilation during the execution of a program at run time rather than compiling it before execution.JIT compilers are actually a combination of 2 approaches to compilation, Ahead of Time Compilers and Interpreters, and combine the pros and cons of both. Generally, Just In Time compilers consolidates the speed of assembled code with the adaptability of translation, with the overhead of a mediator, and the extra overhead of compiling and linking. (JIT Compiler in PHP 8) Major advantages of using Just In Time Compilers: Just In Time compilers require less memory. Page faults can be minimised. While the code is running, it is possible to optimise it using JIT Compiler. Different levels of optimisation can be used. Disadvantages of using JIT Compilers: The time it takes to get up and running can be significant. Cache memory is used extensively. In a Java program, it increases the level of complexity.
