I'm trying to convert this code from Javascript to CoffeeScript:
for (var i = 0; i < names.length; i++) {
str += "Hello" + names[i] + "!<br />";
}
But at the CoffeeScript project home page there is only a simple example of how to do for loops and I can't understand it quite well too, so how can I make convert that to CoffeeScript?
I would do it like this:
msg = ("Hello #{name}!" for name in names).join '\n'
Try this:
str += 'Hello' + name + '!<br />' for name in names
str += "Hello ${name}!<br />" ...
:) @Nathan Does this string interpolation thing work for you? If yes, I'll put it in my answer....
Hello ${name}!<br />Hello ${name}!<br />Hello ${name}!<br />str += "Hello #{name}!<br />". This article suggests that the # sign is used for string interpolation, not the $ sign...# I got this: Hello Nathan,John,Michel!<br />Šime and Acorn beat me to the best answers, but it's worth adding that the literal translation of your code would be
for i in [0...names.length]
str += "Hello #{names[i]}!<br />"
or using postfix rather than indentation,
str += "Hello #{names[i]}!<br />" for i in [0...names.length]
