Specialized Checkers

six ways to disagree

Text

Exact, case, whitespace, Unicode

—

Color

Hex, RGB, HSL, named colors — formats are normalized automatically

—

Number

Decimal, hex, binary, octal

—

Date

ISO strings, timestamps, natural language

—

JSON

Deep structural equality, key order ignored

—

URL

Normalized protocol, host, params
