How to automatically modify variable names in ruby and javascript? -

i want like:

for(var i=0; < 3, i++) { var file_i = i; }

and got local variables: file_0 = 0,file_1 = 1, file_2 =2

i'm want know how create happen in ruby.

if don't mind new variables beingness global:

for(var i=0; < 3, i++) { window["file_" + i] = i; }

but comments have noted, bad idea. create these properties of object:

var files = { }; for(var i=0; < 3; i++) { // <-------- typo there. should ; after < 3 files["file_" + i] = i; }

and can read these properties with:

for (var key in files) { if ({}.hasownproperty.call(files, key)) alert(key + " " + files[key]); }

i'm afraid don't know how ruby.

javascript ruby
