Compound assignment operators (e.g. "+=") #323

Joy-less · 2023-08-10T21:30:58Z

Adds support for: +=, -=, *=, /=, %=, ^=, and ..=.

While these operators are not present in Lua, they are present in Luau and save a lot of time.

Example:

local a = 0
a += 5
print(a)

Converts to:

local a = 0
a = a + 5
print(a)

e.g. local a, b = 1, 2 a, b += 1, 1, 5 print(a) --2 print(b) --3

Prevent e.g: local a += 5
