With elseif you can check multiple situations about same thing.For example you want to do something depends on how much minutes elapsed in game.

if (minutesElapsed < 10) then
    // do something
elseif (minutesElapsed < 30) then
    // do something else
elseif (minutesElapsed < 40) then
    // do something elsee
endif

When first if condition is true, it won't check other if conditions.If minutesElapsed is 5, it makes all 3 conditions true but only the first found one will work.

without elseif you need to do something like this

if (minutesElapsed < 10) then
    // do something
else
    if (minutesElapsed < 30) then
        // do something else
    else
        if (minutesElapsed < 40) then
            // do something elsee
        endif
    endif
endif

Note:elseif just makes your work easier when it needs, it doesn't give you something you can't do.

Sometimes you don't want elseif, but else if. Example, you want actionBC when boolean b or c is true:
not good

if a then
    ...
elseif b then
    actionBC
    ...
elseif c then
    actionBC
    ...
endif

better

if a then
    ...
else
    actionBC
    if b then
        ...
    else
        ...
    endif
endif
