How to name your code follow Uncle Bob way

⛔ Bad code

function card() {
    return card
}

🆗 Good code

function getCard() {
    return card
}

Here the name of the function is self-explanatory, and the variable names give us clues that the cities denote the start and end of something.

Rule 1: Use nouns or short phrases with adjectives to name variables

⛔

let u = {}

🆗

let user = {}

Aim to avoid redundancy in names as much as possible.

Rule 2: The names of the booleans must resolve to a yes or no answer

⛔

if(payment) {
	// do something
}

🆗

if(isValidPayment){
	// do something
}

Booleans have an on/off nature. As such, their names must reflect their character.

Rule 3: Use verbs or short phrases with adjectives to name functions or methods

🆗

function getPaymentMethod() {
 // do something()
}

function fetchWalletBalance(wallet Wallet) {
 return wallet.balance
}

Avoid inconsistencies when using verbs for naming functions and stick to using the same verbs for the same actions.

Rule 4: Use nouns or short phrases with nouns to name classes

⛔

class AppUser {
  // some methods/vars
}

🆗

class User {
  // some methods/vars
}

To avoid any confusion, make sure to use nouns and think before adding an extra word to the name.

Does it add any value, or does it make the meaning fuzzier?
