Go Conditions

Go (Golang) – Conditions (Decision Making)

Conditional statements in Go are used to execute different blocks of code based on true or false conditions.
Go keeps condition syntax simple and strict.

1️⃣ if Statement

Syntax


Example


 

2️⃣ if–else Statement


 

3️⃣ if–else if–else Ladder


 

4️⃣ if with Short Statement (Very Common)

Go allows a short initialization statement inside if.


⚠ x is only accessible inside the if block.

5️⃣ Logical Conditions


 

6️⃣ Nested if Statements


 

7️⃣ switch Statement (Alternative to if–else)

Basic switch


 

✔ No break needed (auto break)

8️⃣ Multiple Values in case

// ❌ Invalid
if (age > 18)// ✅ Valid

}
