This is probably not what you wanted to hear, but I’m glad they don’t optimize for Ramda. On projects where I’ve had to use it, it just generally results in a bunch of fanciful syntax flourishes from the Ramda enthusiast on the team. They’ll jump on anything that looks like array manipulation, eager to try some neat Ramda tricks. In the end a “dumb” solution with loops usually ends up being shorter and simpler (not to mention, much easier on the memory without all the copying), and this is the style of code that Typescript optimizes for.
