Functions are like variables, you can put them into variables and use them.
look at this example:
func hello($name)
println('hello ' + $name)
endfunc
hello('parsa')
# puting the function into the variable
$myfunc = hello
# calling the variable
$myfunc('pashmak')
output:
hello parsa
hello pashmak
another example:
func somefunc()
println('hello. I has been ran')
endfunc
$myfunc = somefunc
$myfunc()
also look at this example:
func run_the_func($func)
println('start')
$func()
println('finish')
endfunc
func hi
println('hello world')
endfunc
run_the_func(hi)
Also you can change value of functions. functions are like variables and can be changed.
For example:
func hi
println('Hi')
endfunc
func bye
println('Bye')
endfunc
hi()
bye()
output:
Hi
Bye
Now We can change value of this functions:
hi = bye
hi()
output:
Bye
Actually, in above example, We are setting bye into hi.
