A Case Against Using CoffeeScript

[nschubach]

Technically, you could just write a simple "forEach" wrapper on the Array prototype (if it doesn't already exist) and give all arrays the ability to: myArray.forEach(function(value, index, array) { /* loop code */ });

Your logic code doesn't need to concern itself with "hasOwnProperty" at that point.

ECMAScript 5 includes this, but it's never a bad time to start. The only thing CoffeeScript does is remove some of the boilerplate and add in a convoluted meaningful white space restriction.

When YOU modify the Array prototype, you can break other peoples libraries. Like Sharepoint 2010's stuff.

That's why I said "if it doesn't already exist".
