Multiple conditions in for loop

Question

How can I write a for loop with multiple conditions?

Intended Javascript:

for(k=1; k < 120 && myThing.someValue > 1234; k++){
  myThing.action();
}

js2coffee.org indicates that I should use a while loop:

k = 1
while k < 120 and myThing.someValue > 1234
  myThing.action()
  k++

but this ends up compiling back to a while loop in javascript.

Is there a way to write coffescript to compile to my intended javascript and include extra conditions in the for loop itself?

If the answer to that question is false, then what would be the nicest way to get the same functionality with coffeescript?

My best while loop solution so far is

k = 1
myThing.action() while k++ < 120 and myThing.someValue > 1234

Answer 1

Since a for loop is equivalent to a while loop plus a couple of statements, and CoffeeScript offers only one kind of for loop, use a while loop. If you’re trying to get specific JavaScript output, you should probably not be using CoffeeScript.

Of course, there is always

`for(k=1; k < 120 && myThing.someValue > 1234; k++) {`
do myThing.action
`}`

Avoid.
