Source Code
/sȯrs kōd/
noun — "the readable form of instructions a system turns into action."
Source Code is the human-readable set of instructions written by programmers that defines how a program behaves. It is the original form of software before it is transformed into machine-executable form by compilers, interpreters, or other processing tools.
Source code is written in programming languages such as C, Python, JavaScript, or many others. These languages exist to express logic in a way humans can understand while still being precise enough for machines to execute.
