Scratch is a visual programming language. For the sake of counting bytes, Scratch is usually written in scratchblocks2 syntax.
Post tips that specifically apply to Scratch or scratchblocks2.

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
1
In Scratch the true and false values are equivalent to 0 and 1, so you can perform arithmetic operations over them. A practical example would be finding the sign of a number:
define f(n
set[r v]to(<(n)>(0)>-<(n)<(0
0
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.
For example:
define f(n
say((n)+(1
Over:
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 n.

A few people might also use the scoring here (in the question post itself), although the two scores definitely don't compete. BTW, Scratch 3.0 will be released in January, but the syntax, AFAICT, isn't going to change much.
