Compound Operators
Pluto implements a plethora of compound operators, which are actually faster than their Lua counterparts.
Additions
- Modulo:
%= - Addition:
+= - Exponent:
^= - Bitwise OR:
|= - Subtraction:
-= - Bitshift left:
<<= - Bitwise AND:
&= - Float division:
/= - Bitshift right:
>>= - Multiplication:
*= - Concatenation:
..= - Integer division:
//= - Null-Coalescing:
??=
Why are they faster?
They store their left-operand in a temporary register, which reduces a lookup & makes them roughly 30% faster.
Example Code
local a = 5
-- Old
a = a + 5
-- New
a += 5
