Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
Follow-up research found little evidence of the predicted cognitive benefits of programming education, and the rise of the software industry and graphical user interfaces caused educational focus to shift in the 1990s toward end-user skills. [1] Computers were also expensive, limiting the integration of coding skills into the school curriculum.

A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, agile software development, rapid application development, and extreme programming.
These solutions do not require traditional programming and may be based around relatively narrow functionality, e.g. contract management, customer relationships management, issue and bug tracking. Often referred to as low code development platforms, web based interactions guide a user to develop an application in as little as 40–80 hours.

Ad hoc code reuse has been practiced from the earliest days of programming.Programmers have always reused sections of code, templates, functions, and procedures. Software reuse as a recognized area of study in software engineering, however, dates only from 1968 when Douglas McIlroy of Bell Laboratories proposed basing the software industry on reusable components.
