Answer: Development, or "dev", is a process of creating software or other products through coding, testing, and debugging. It involves taking an idea or concept and turning it into a working product. Development requires a deep understanding of the product's purpose, the technologies used to create it, and the customer's needs. It also requires a lot of collaboration between developers, designers, and other stakeholders. The development process is iterative and often involves multiple cycles of design, coding, testing, and debugging in order to create a high-quality product that meets the customer's needs.
