ArrowFunctionsForCallbacks [rule] v0.1.0

When the function is anonymous and passed inline as an argument or assigned to a binding, use an arrow function. Arrow functions inherit this from the enclosing scope, are terser, and signal "this is not a method, just a value-returning expression" at the call site.

Checks

• array.map((x) => x.id) rather than array.map(function (x) { return x.id }).
• Single-expression arrow bodies omit braces and return: (x) => x.id, not (x) => { return x.id }.
• Use parentheses around the parameter list whenever there are zero, two-or-more, or destructured parameters; many teams require parens always for consistency (Airbnb does).
• ESLint prefer-arrow-callback and arrow-body-style are configured.
