default-param-last

强制默认参数位于最后。

此规则扩展了基本规则 eslint/default-param-last。它添加了对可选参数的支持。

❌ 错误

function f(a = 0, b: number) {}
function f(a: number, b = 0, c: number) {}
function f(a: number, b?: number, c: number) {}
class Foo {
  constructor(
    public a = 10,
    private b: number,
  ) {}
}
class Foo {
  constructor(
    public a?: number,
    private b: number,
  ) {}
}

✅ 正确

function f(a = 0) {}
function f(a: number, b = 0) {}
function f(a: number, b?: number) {}
function f(a: number, b?: number, c = 0) {}
function f(a: number, b = 0, c?: number) {}
class Foo {
  constructor(
    public a,
    private b = 0,
  ) {}
}
class Foo {
  constructor(
    public a,
    private b?: number,
  ) {}
}

module.exports = {
  "rules": {

  }
};
