Rules

arrow-parens

This rule works like vanilla arrow-parens, but provides an additional setting for functions that use currying.

/* eslint curry/arrow-parens: [2, "as-needed", { "requireForBlockBody": true, "curry": "never" }] */
// bad
const fn = (x) => x
const fn = x => {}
const fn = (x) => (y) => (z) => {}
 
// good
const fn = x => x
const fn = (x) => {}
const fn = x => y => z => {}
