JavaScript Conditional Statements Guide

Yapay zekadan makale özeti

Basic If-Else Statements: If-else statements execute code when condition is true
Falsy values include false, 0, empty string, null, undefined, NaN
Multiple conditions can be tested using else if blocks
Logical Operators: Logical AND (&&) requires both conditions to be true
Logical OR (||) executes code if at least one condition is true
Logical NOT (!) reverses the truth value of a condition
Alternative Approaches: Switch statements offer cleaner syntax than if-else
Ternary operator provides shorter alternative to if-else
