How does creating a framework work?
When people create web frameworks or other languages do they use low level languages like assembly or do they just use another language? for example, the ajax framework, is that acutally javascript, with methods defined in javascript syntax and code, or is it a language that someone had to make a seperate compiler for and made it to work within the javascript framework?
