    Rule Details

    Default parameters are most useful at the end of a parameter list, where callers can omit them. This rule reports default or optional parameters followed by required parameters.

    Examples of incorrect code for this rule:

    function createUser(isAdmin = false, id) {}

function connect(host = "localhost", port) {}

    Examples of correct code for this rule:

    function createUser(id, isAdmin = false) {}

function connect(port, host = "localhost") {}

    The rule also supports TypeScript optional parameters and parameter properties.

    Examples of incorrect TypeScript code for this rule:

    function format(value?: string, radix: number) {}

class Client {
  constructor(public endpoint = "localhost", private retries: number) {}
}

    Examples of correct TypeScript code for this rule:

    function format(radix: number, value?: string) {}

class Client {
  constructor(private retries: number, public endpoint = "localhost") {}
}
