enforce default parameters to be last (default-param-last)

Putting default parameter at last allows function calls to omit optional tail arguments.

// Correct: optional argument can be omitted
function createUser(id, isAdmin = false) {}
createUser("tabby")

// Incorrect: optional argument can **not** be omitted
function createUser(isAdmin = false, id) {}
createUser(undefined, "tabby")
