Editing Compilers and Programming Languages (section)

* '''Programming Language''' — A formal language comprising a set of instructions that produce various kinds of output.
* '''Compiler''' — A program that translates code from a high-level language to a lower-level language (like machine code) all at once.
* '''Interpreter''' — A program that translates and executes code line-by-line (e.g., Python, JavaScript).
* '''Source Code''' — The human-readable version of a program.
* '''Machine Code''' — The binary instructions executed directly by the CPU.
* '''Assembly Language''' — A low-level language that is a human-readable version of machine code.
* '''Syntax''' — The set of rules that defines the combinations of symbols that are considered to be a correctly structured document or fragment in that language.
* '''Lexical Analysis (Lexing)''' — The first stage of a compiler; breaking code into "tokens" (like keywords, variables, and operators).
* '''Parsing''' — The second stage; organizing tokens into a "Syntax Tree" to check if the grammar is correct.
* '''Optimization''' — The process where the compiler modifies the code to make it run faster or use less memory.
* '''Type System''' — A set of rules that assigns a "type" (like integer or string) to variables to prevent errors.
* '''Garbage Collection''' — An automatic memory management system that finds and deletes objects that are no longer being used.
* '''Transpiler''' — A compiler that translates from one high-level language to another (e.g., TypeScript to JavaScript).
