Scratch is a visual programming language. For the sake of counting bytes, Scratch is usually written in scratchblocks2 syntax.

In the scratchblocks3 visual syntax (backwards-compatible with scratckblocks2 syntax), you can auto-complete the brackets.
E.g. The hello, world program:
when gf clicked say[hello, world]
Can be golfed into:
when gf clicked say[hello, world
In addition, the end statement of switching structures is auto-completed at the end. So instead of
define f(n set[i v]to(1 set[o v]to( repeat(length of(n repeat((2)-((i)mod(2 set[o v]to(join(o)(letter(i)of(n end change[i v]by(1
You could do (-4 bytes)
define f(n set[i v]to(0 set[o v]to( repeat(length of(n change[i v]by(1 repeat((2)-((i)mod(2 set[o v]to(join(o)(letter(i)of(n
Where possible, if the challenge says functions are allowed, use them! The syntax for defining a function is almost always shorter than the usual
when gf clicked.
define f(n say((n)+(1
when gf clicked ask()and wait say((answer)+(1
This also means one doesn't have to use the
answer variable, which is quite longer than
