How many paremeters would be considered bad code while passing to a function? 5? 10? Whats the unwritten rule?

Hello, @⛄Snowberb⛄ very good question Depends on your definition from clean code; My understand is that : - 2 is optimal - 3 maximum - if more than 2 or 3 , use a configuration object I've recently become a clean code enthusiast and that's what I learned

what's a configuration object? @Liil' Boo

const updateFavoriteProp = async (UUID, accountId, isFavorite, isShared, services, entities, accounts, setErrors) => {
  try {
    const updatedAccount = await updatePartialAccountInfo(UUID, accountId, { isFavorite: !isFavorite });

    return {
      ...updatedAccount,
      serviceType: getServiceType(updatedAccount.serviceType.serviceTypeId, services),
      accountType: updatedAccount.accountType.description['es-ES'],
      entity: getEntityType(updatedAccount.accountType.accountTypeId, entities),
      isShared,
    };
  } catch (e) {
    e instanceof Array
      ? setErrors(e)
      : setErrors(['No se ha podido actualizar la cuenta favorita, por favor intentelo mas tarde']);
  }
};

const updateFavoriteProp = async (UUID, accountId, isFavorite, isShared, services, entities, accounts, setErrors) => {
  try {
    const updatedAccount = await updatePartialAccountInfo(UUID, accountId, { isFavorite: !isFavorite });

    return {
      ...updatedAccount,
      serviceType: getServiceType(updatedAccount.serviceType.serviceTypeId, services),
      accountType: updatedAccount.accountType.description['es-ES'],
      entity: getEntityType(updatedAccount.accountType.accountTypeId, entities),
      isShared,
    };
  } catch (e) {
    e instanceof Array
      ? setErrors(e)
      : setErrors(['No se ha podido actualizar la cuenta favorita, por favor intentelo mas tarde']);
  }
};

This is the function im talking about I took it out of the main component to a service file to atomize and structure it better

but then I have this in the main componenet

(screenshot because its more readable)

Hmm... I'm not strong enough to explain what' a configuration object If you do some research on : IntersectionObserver , or ResizeObserver You'll see both take a configuration object I'mma try to show you by refactoring your function

SniberbOP•3y ago

thank you! Im also trying to write the cleanest code possible

liil'boo•3y ago

type UUID = string;
type Services = any[]
type Entities = any[]
type Accounts = any[]
type ID = number | string
type configurationObject = {
isFavorite : boolean,
isShared : boolean,
services : Services,
entities : Entities,
accounts: Accounts,
setErrors : () => void,
}

function updateFavoriteProp(uuid : UUID, accountId : ID, object: configurationObject){
//...your code
}

updateFavoriteProp('uuid', 2, { isShared: true, isFavorite: true});

type UUID = string;
type Services = any[]
type Entities = any[]
type Accounts = any[]
type ID = number | string
type configurationObject = {
isFavorite : boolean,
isShared : boolean,
services : Services,
entities : Entities,
accounts: Accounts,
setErrors : () => void,
}

function updateFavoriteProp(uuid : UUID, accountId : ID, object: configurationObject){
//...your code
}

updateFavoriteProp('uuid', 2, { isShared: true, isFavorite: true});

A configuration object allows you to only pass in what you need and not bother about the order of arguments/parameters Looks like you already have one for the function updateAccount

oh okay yeah I get it now

liil'boo•3y ago

Your original function might be missing some 'null checks' also

SniberbOP•3y ago

the whole project is missing null checks its js not ts xd

liil'boo•3y ago

TS > JS

SniberbOP•3y ago

literally try telling that to my coworkers

liil'boo•3y ago

hard to do clean code without typescript

SniberbOP•3y ago

pretty damn hard yes well thank you so much for the info

liil'boo•3y ago

Javascript is like, dirty by default, and fight to make it cleaner

SniberbOP•3y ago

appreciated it

liil'boo•3y ago

Gotta give back to the community
