Conditionals (if / else)
if checks a condition and runs code only when it's true. else runs when it's false, and elseif checks another condition in between. Conditions almost always use comparison or logical operators inside the parentheses.
Why this matters
- ·Lets a script make decisions instead of always doing the same thing
- ·elseif chains handle many cases cleanly
Common mistakes
- ·Missing curly braces around a multi-line if block causes only the first line to run conditionally
- ·Forgetting elseif and stacking separate if statements can run more than one block by mistake
