图片来自:The Thing from another World Interpreter(解释器) 解释器是一种直接执行高级语言代码的计算机程序, 而无需将代码编译成机器码. 优点: 消除了编译整个程序的负担,程序可以拆分成多个部分来模块化. 缺点: 解释器像是一位“中间人”,每次运行程序时都要先将代码转成另一种语言的代码,然后再作运行,因此解释...
编译器(Compiler)和解释器(Interpreter)是两种不同的工具,都可以将编程语言和脚本语言转换为机器语言。
Compiler and Interpreter are two different ways to translate a program from programming or scripting language to machine language. Acompilertakes entire program and converts it into object code which is typically stored in a file. The object code is also referred as binary code and can be direct...
这里的优化其实指的就是 JIT 直接假设一个前提,比如这里我们直接假设 sum 是 Int,i 也是 Int,arr 是 Array,于是就只用一种编译结果就好了。 实际上,在执行前会做类型检查,看是假设是否成立,如果不成立执行就会被打回interpreter或者 baseline compiler 的版本,这个操作叫做 "反优化 (deoptimization)"。 可以看出,...

compiler, look at the words themselves, inter means between, the interpreter is always between your program and the computer, and it translates line by line. To compile on the other hand means to pile together, a compiler piles together your entire program and translates the whole thing all ...
