UTF-8 encoding can represent over 1.1 million characters, covering every writing system in the Unicode standard.

JSON was derived from JavaScript but is now language-independent and used by virtually every modern programming language and web API.

Essential Terms

Hashing: A one-way function that maps data of arbitrary size to a fixed-size output. Hashes are used for data integrity verification, password storage, and digital signatures.
YAML (YAML Ain't Markup Language): A human-readable data serialization format commonly used for configuration files. YAML uses indentation for structure, making it easier to read than JSON for complex nested data.
Syntax Highlighting: A feature of text editors and code viewers that displays source code in different colors and fonts according to the category of terms. This visual differentiation improves readability and helps catch syntax errors.
UTF-8 (Unicode Transformation Format): A variable-length character encoding that can represent every character in the Unicode standard. UTF-8 is backward-compatible with ASCII and is the dominant encoding on the web.
