When writing HTML or XML documents, it's essential to escape special characters, e.g., < and > must be written as < and > respectively, to avoid breaking the markup structure.Similarly, the ampersand (&) must be encoded as & when used in text to prevent confusion with character entities.
Developers often forget this during quick updates, which can lead to rendering issues & validation errors in the final output.To maintain clean code, it's good practice to include newline characters (\n) where appropriate, especially in log files or config files.These simple steps ensure the code is both machine-readable and human-friendly—> helping teams avoid unexpected bugs.
