3.3 If Else Statements

Purpose of Else Statements

Else statements: Handles what happens when the if condition is false. Structure of If-Else:

• If statement with a condition.
• Else statement without a condition.
• Both parts have code blocks surrounded by {}.

don’t forget the brackets

int x = 20;
if (x > 10) {

    console.log("x is greater than 10");
    console.log("This code when the condition is true");
    } else {
    
    console.log("x is 10 or less");
    console.log("This code runs when the condition is false");
}
//    Without brackets:
        
   console.log("x is greater than 10");
   console.log("this code will always run");

|       console.log("x is greater than 10");
