JavaScript Operators in JavaScript

Arithmetic: + - * / % ** (exponent). Modulo (%) gives remainder: 10 % 3 = 1.

Comparison: == (loose equal, ignores type), === (strict equal, checks type too). Always use ===. != loose, !== strict.

Logical: && (AND), || (OR), ! (NOT). Short-circuit: a && b returns b if a is truthy, a if a is falsy.

Assignment: = += -= *= /= **= ??= (nullish). Ternary: condition ? valueIfTrue : valueIfFalse.
