This document introduces coding and its benefits. It defines coding as writing instructions that computers can understand to communicate with and direct them. Coding helps develop critical thinking, problem solving, creative thinking, resilience, and communication skills. It explains that computers only understand binary code consisting of 0s and 1s, so programming languages are used to more easily write code that then gets translated to binary. Popular languages include JavaScript, Python, Java, Ruby, and PHP. Different languages are used for different purposes like web development, software/apps, and scientific applications.
