+⛔ Bad code
+
+```go
+function card() {
+    return card
+}
+```
+
+🆗 Good code
+
+```go
+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
+
+⛔ 
+```go
+let u = {}
+```
+
+🆗 
+
+```go
+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
+
+⛔
+```go
+if(payment) {
+	// do something
+}
+```
+🆗 
+```go
+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
+
+🆗
+```go
+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
+
+⛔
+```javascript
+class AppUser {
+	// some methods/vars
+}
+```
+🆗
+```javascript
+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?*
