Rules

Commas

• 1 Additional trailing comma: Nope.

Airbnb [states] that this rule makes git diffs cleaner, though we don't really see any significant value in this especially for Arrays or Objects that only have one item.

// bad const hero = { firstName: 'Dana', lastName: 'Scully', };

const heroes = [ 'Batman', 'Superman', ];

// good const hero = { firstName: 'Dana', lastName: 'Scully' };

const heroes = [ 'Batman', 'Superman' ];
