rbxts-transformer-switchcase v1.0.1

rbxts-transformer-switchcase

Converts switch cases into simple if else blocks, to make it faster and to make it more legible.

Example

let a = 2

switch (a) {
    case 1:
        print("one");
        break;

    case 2:
        print("two");
        break;

    default:
        print("uhh what??");
        break;
}

local a = 2
repeat
    if a == 1 then
        print("one")
        break
    end
    if a == 2 then
        print("two")
        break
    end
    print("uhh what??")
    break
until true

local a = 2
-- switch
if a == 1 then
    print("one")
    -- break
elseif a == 2 then
    print("two")
    -- break
else
    print("uhh what??")
    -- break
end
