Conditional Statements
if, else, switch statements
javascript
// if/else
if (condition) {
// code
} else if (otherCondition) {
// code
} else {
// code
}
// switch
switch (value) {
case 'a':
// code
break;
case 'b':
// code
break;
default:
// code
}💡 Always use braces {} even for single-line if statements
⚡ Switch uses strict equality (===) for comparisons
📌 Don't forget break in switch cases to prevent fall-through
🔥 Switch is cleaner than multiple if/else for many conditions
