I find livecode's "do" command something like magic.
Is there something like it in Python, or JavaScript?

what's magic for me is the [each] iterator... don't think there's anything like it in other languages and it makes such easy work of it...

And FAST, if you mean in the "Repeat for each..." form.

But just as cool is the "each" local variable, which allows one to, say: Magic, as you say.

Code: Select all

sort lines of myHugeList by word 3 and item 5 of each

Actually repeat for each is a common pattern across several languages... (and until we get compiled scripts, all of these are faster...)

i meant the second form you mention - also when filtering arrays, so versatile

In both javascript and python the "do" equivalent is In both javascript and python this function is discouraged because it can enable arbitrary code to run, which may be a big security risk. The same risk is applicable in LiveCode but I dare say there is a smaller possibility of attack through this vector.
