Programming languages

1. programming language

   • need compiler to execute the program
     • The compiler is a program which translate the code fom a high-level language to a low-language,The compiler do this operation just once, differently to the interpreter which works on loop .  The compiler does take some time to tansmate the mangauages but it does it efficiently and optimatizes the code, but it can generte a not very good code sometimes.

2. scripting languages

   • There are two types of scripting  languages : +  server-side S L : used to solve errors and problems. such as java, python and ruby .... + client-side  : concerned by functionality and design; such as HTML, CSS and Javascript.
   • need an interpreter to run the program
     • An interpreter run directly the program, meanwhile the compiler needs to make the the code executable just once and then the program runs the same way everytime.
