cons (push) opposite: unshift?

[oluckyman]

Is there the opposite for cons? which will insert an element into beginning?
And if no, what's the shades-style to achieve it?

[jamesmcnamara]

As of shades@2.1.0-beta.1, there's an unshift function!

> unshift(1)([2, 3, 4])
[1, 2, 3, 4]

You can grab it by doing

npm install shades@beta

Or if you want to stick with the stable branch, you can do:

> prepend([1])([2, 3, 4])
[1, 2, 3, 4]

Note that prepend requires that the first element be a list as well.

ah, thanks! missed the prepend or was not aware that it's what I need. Ended up by using

x => xs => [x, ...xs]

which is pretty concise too.
