Your Code Doesn't Run. A Translation of Your Code Does.

The article explains the compiler pipeline that turns source code into machine code, step by step.

It starts with lexing and tokenization, then parsing to build an AST, followed by semantic analysis to validate correctness.

Next, the code is lowered into an intermediate representation and finally translated into machine instructions for the CPU.

Along the way, it uses examples to show why syntax errors and other compiler errors happen.
