When writing markup-based languages like HTML or XML, it is crucial to handle special characters properly —e.g., <, >, and & must be encoded as <, >, and & respectively. Improper handling can lead to broken layouts, security issues, or unintended browser behaviors. Developers often rely on formatting, such as multiple spaces and tab-separated\tvalues, to improve readability or align elements in source code. Though browsers collapse whitespace visually, maintaining clean structure in the codebase helps with debugging and team collaboration. In many programming scenarios, inserting \n (newline) characters is useful for logging, data serialization, or content display formatting.\tProper use of tabs and consistent spacing practices make the difference between readable and hard-to-maintain code.
