A coder is someone who writes instructions for computers using programming languages like Python, Java, or JavaScript. These instructions, known as code, tell the computer what to do, such as creating websites, apps, or games. Coders can work on various projects, from simple tasks to complex software systems, and their work is essential in today's technology-driven world. Many coders start by learning the basics of coding through online courses or coding bootcamps. They often collaborate with other professionals, such as designers and project managers, to bring their ideas to life. With the growing demand for technology, coding skills are increasingly valuable in many industries.
