松脚本函数返回

Question

I'm confused by pine scripts returns from functions, why does this code show a 3 and not a 1 ? Shouldn't execution stop as soon as possible?

//@version=5
indicator("Test functions", overlay = true)

returnFunction() =>
    1
    2
    3
label.new(bar_index, high, str.tostring(returnFunction()))

Answer 1

The value that's returned by a multi-line function is the function's last line (Pine Script Language Tutorial, nd). That line can either be an expression (like x + 10), a variable (x), or a variable declaration (x = 10).
