Coding is the composition of sequences of instructions that computers can follow to perform tasks.
It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit.
Coding essentially acts as a mental workout that challenges your logical thinking, problem-solving skills, and ability to translate complex ideas into instructions a computer can understand, similar to how a math problem or puzzle would exercise your brain.
