Code Style

Indentation & Width

• Use tabs for indentation.
• Soft line limit at 80 characters.

Punctuation & Types

• No semicolons.
• Prefer Array notation over T[].

Control Flow

• No for/while loops—use toolsmith functions (map, filter, reduce, etc.).

Spacing

• Spaces around all operators: x + y not x+y.
• Object spacing: { x: 7 } not {x:7}; space after colons.
• Arrays: space after commas: [1, 2, 3] not [1,2,3].
• Function params: (a, b) not (a,b).

Trailing Commas

• Always in multi-line arrays, objects, and parameter lists.
• Never in single-line structures.

Blank Lines (explicit rules)

• No blank lines at the top or bottom of a block.
• Insert a blank line before return statements.
• Insert a blank line above and below any statement that spans multiple lines.
• Insert a blank line between different statement types (e.g., const → if, if → return, const → assertEquals).
• Group const declarations at top with a single blank line below the group (not above).
• Add a blank line before help comments (//??).
• Never more than one blank line in a row.
