Programming language implementation
open-in-new
<p>In <a href="/facts/Computer_programming/QmSsFnu0">computer programming</a>, a programming language implementation is a system for executing <a href="/facts/Computer_programs/e38jH9N9">computer programs</a>. There are two general approaches to programming language implementation: </p> <ul><li><i><a href="/facts/Interpreter_(computing)/JB85fbyb">Interpretation</a>:</i> The program is read as input by an interpreter, which performs the actions written in the program.</li> <li><i><a href="/facts/Compiler/WNfCDFJe">Compilation</a>:</i> The program is read by a compiler, which translates it into some other language, such as <a href="/facts/Bytecode/EPkMFR7M">bytecode</a> or <a href="/facts/Machine_code/bgdQ1Fxf">machine code</a>. The translated code may either be directly <a href="/facts/Execution_(computing)/1fyfGMFm">executed</a> by hardware or serve as input to another interpreter or another compiler.</li></ul>
