what is aspect weaver? A metaprogramming utility for aspect-oriented languages what is it used for? It is designed to take instructions specified by aspects  and generate the final implementation code. what was the motivation behind this? The desire to create radically different programming languages to support the aspect-oriented programming paradigm is not significant due to business-related concerns, thus, to address these business concerns, an aspect weaver enables the use of widely adopted languages what is done in aspectj weaving? In the programming language AspectJ, pointcuts, join points, and the modularized code are defined in an aspect block similar to that of Java classes what is the definition of a language for programming? A programming language is a notation for writing programs, which are specifications of a computation or algorithm. can you name any early developers? Very early computers, such as Colossus, were programmed without the help of a stored program, by modifying their circuitry or setting banks of physical controls what are the elements of these languages? All programming languages have some primitive building blocks, these primitives are defined by syntactic and semantic rules

Programming language [SEP] Elements
All programming languages have some primitive building blocks for the description of data and the processes or transformations applied to them (like the addition of two numbers or the selection of an item from a collection). These primitives are defined by syntactic and semantic rules which describe their structure and meaning respectively.
