lua scripts, end or end; ?

[dklfcheat]

when using scripts like:

/run if IsUsableSpell("Blood strike") and IsSpellInRange("blood strike", "target")==1 then CastSpellByName("Blood strike") end
/run if IsUsableSpell("Blood strike") and IsSpellInRange("blood strike", "target")==1 then CastSpellByName("Blood strike") end

are we supposed to actually put ; at the end except for the last one or what, whats the logic or explanation behind this, im just looking to make my scripts better

/run if IsUsableSpell("Blood strike") and IsSpellInRange("blood strike", "target")==1 then CastSpellByName("Blood strike") end;
/run if IsUsableSpell("Blood strike") and IsSpellInRange("blood strike", "target")==1 then CastSpellByName("Blood strike") end

i also seen scripts end with more than one "end" like:

/run if IsUsableSpell("Blood strike") and IsSpellInRange("blood strike", "target")==1 then CastSpellByName("Blood strike") end end

You use the semi colon to highlight that you're doing more than one thing in a single line
