❓ Conditional Statements (Conditional Statements)?
Conditional Statements code condition (true) (false).
code No No only ✨
let age = 20;
if (age >= 18) {

⚖️ 5️⃣ Nested if vs Logical AND (&&)
Nested if operator && code.
// Nested if
if (age >= 18) {
if (hasLicense) {
message = "You can drive.";
}
}
// using && ( )
if (age >= 18 && hasLicense) {
message = "You can drive.";
}
if (age >= 18) {
if (hasLicense) {
message = "You can drive.";
}
}
// using && ( )
if (age >= 18 && hasLicense) {
message = "You can drive.";
}
